Madonna will pay special tribute to Michael Jackson when she resumes her Sticky & Sweet tour in London tomorrow night.

Madonna's rep tells the Associated Press that she'll perform a special song and dance number in memory of Michael during the concert.

In exclusive photos of a dress rehearsal for the show (posted on Madonna's Web site), a man dressed like the late King of Pop is pictured busting dance moves while the Material Mom and an entourage watch on, looking impressed.

What kind of music was the King of Pop dreaming up before he died? Read on for the dish.

The late star was at work on a pop album and classical, instrumental pieces, says Billboard.com. On the pop album, he was collaborating with songwriter Claude Kelly and R&B star Akon, who says Michael was inspired by popular demand for tickets to his shows.

"He said, 'My fans are still there. They still love me. They're alive,'" Akon says. "His kids are like his first priority, and they had never seen him perform live. He was trying to create the most incredible show for his kids."

Michael Jackson was busy putting on the final touches for his 50-date London concerts at the O2 Arena when he unexpectedly died. Now, ET's Thea Andrews is with the men behind the massive production to reveal what could have been Michael's most incredible concert tour yet!

A show filled with music, dance, stunts and pyrotechnics, Michael's "This is It" concert was being directed by Kenny Ortega, the man who designed Michael's "Dangerous" tour, choreographed 'Dirty Dancing' and also brought "High School Musical" to the world. Kenny says that Michael promised "the concert of a lifetime" and was prepared to deliver.

"We [had] some fun things planned," he says, referring to gigantic spiders, 20-foot puppets, a flaming bed, a pole dancing aerialist, a 3D movie and plenty more magic. "It's complex in scale and it's as big as anything I've ever done or attempted to do for an arena production."

The time, date and ticket-availability info for Michael Jackson's public memorial have been announced.

The farewell service for Jackson will take place on Tuesday, July 7 at 10 a.m. at the Staples Center. Eleven thousand tickets will be made available to the general public free of charge.

The program will also be simulcast at Los Angeles' nearby Nokia Theatre.

ET has just obtained the footage from one of Michael Jackson's final rehearsals, shot just two days before his death on June 23.

He appears strong and when he finishes the song he is all smiles.

In these photos, Michael is seen with loved ones at his grandmother's funeral in 1990. The photos were taken at the Jackson family burial plot at Forest Lawn Cemetery in Los Angeles.

Matt Fiddes, a former bodyguard of Michael Jackson, is opening up in new video footage about what he experienced when he worked with the King of Pop, and hints that Michael may have been in a relationship with a woman.

Fiddes speaks in the video at length about things he witnessed with Jackson associate and renowned paranormalist Uri Geller. "Uri confiscated injection equipment from his room and whisked it away, and Uri would scream intensely at Michael to stop doing this," Fiddes says.

Fiddes tells the interviewer that one morning "[Michael] was hard to wake." "We were extremely concerned," Fiddes says, continuing, "and I can remember it clearly now, Michael was there and Uri was shaking him saying, 'Michael, have you taken something?' and he would come round and just say it was jet lag."

Hollywood.tv was on hand to capture the scene.

Michael Jackson's ex-wife will be represented by a lawyer at a Monday hearing to determine custody of her children with Jackson.

There is no word on whether Rowe will seek custody of Jackson's two older children, Michael "Prince" and Paris-Michael, both of whom she gave birth to, but ET can confirm that her lawyer, Eric George, will represent her interests at this coming Monday's custody hearing.

A 2002 will for the King of Pop leaves custody of his children, including 7-year-old Prince Michael "Blanket" (who was delivered via surrogate) to his mother, Katherine Jackson, with Diana Ross as a back-up if Katherine was unable to care for the children. All three children are currently in Katherine's care.

A public memorial service for Michael Jackson will be held at the Staples Center, a sports arena in Los Angeles.

Jermaine Jackson is speaking out about his brother Michael Jackson's death -- and he makes a shocking admission about the King of Pop's passing.

The 54-year-old Jackson brother said Thursday during an interview with Matt Lauer on NBC's "Today Show" that he would like Michael to be laid to rest at Neverland Ranch, and he reveals that he wishes he had died instead of his younger brother.

He also told Matt that his family brought Michael Jackson's three children Michael "Prince," Paris-Michael and Prince "Blanket," to see Michael's body after he passed away. Jermaine told Matt, "The therapist thought it was important for them to see their father ... so they could understand." He continued on to say, "But now they're fine. I know it's tough, but I think it was the best thing to do."

This week a shocking report surfaced claiming that the biological father of Michael Jackson's children is actually the King of Pop's one-time doctor -- and Debbie Rowe's former boss -- Beverly Hills dermatologist Arnold Klein. Now, ET recruits a board certified plastic surgeon to do a comparative facial analysis of the children!

"When you examine the pictures of Dr. Klein and try to compare them to Prince and Paris, there really is very little resemblance between the two," says Dr. Brian S. Glatt. "It seems to me that he would be very unlikely to be genetically related to them."

Looking at certain "giveaway" facial features such as the nose, eye color, hair color and facial structure, Dr. Glatt says there is very little similarity in appearance other than the fact that Dr. Klein and the children have light-colored skin.

Investigative journalist Diane Dimond, who has been covering Michael Jackson since 1993, talks to ET about the latest bombshell from the King of Pop's will.

Earlier today, ET reported that Michael Jackson's will states that if his mother, Katherine Jackson, is unable to raise his children, he would like Diana Ross to take over the care of his kids.

"Michael always idolized Diana Ross," Diane tells ET. "There were reports he always wanted to look like her. When Michael and his brothers first moved to Hollywood, Motown sent them out ahead of the rest of the family. Katherine Jackson was beside herself that her son was living with Diana Ross. She's always felt a jealousy with Diana Ross. I can't see how this pleases Katherine Jackson one iota."

The Jackson family has released a statement about reports that a public memorial for Michael Jackson would be held at Jackson's former home, Neverland Ranch.

"Contrary to previous news reports, the Jackson family is officially stating that there will be no public or private viewing at Neverland. Plans are underway regarding a public memorial for Michael Jackson, and we will announce those plans shortly," a rep for the family said in a statement.

It is Mark's opinion that Michael would never have contemplated setting such a tough performance schedule if he "wasn't on top of it." Mark also tells ET, "If he couldn't have done it, he wouldn't have done it."

Katherine Jackson was deemed temporary special administrator of her son's estate earlier this week when it was believed that Michael did not have a will. After the will was filed, executors of the will requested that they have control over the singer's assets, the Associated Press reports.

According to AP, a probate hearing has been scheduled for Monday, of which time Katherine could lose her temporary rights as the administrator of the estate.
