What had ETOnline readers buzzing this week?

1. Gabby Douglas Surprised by 'Vampire Diaries' Cast

16-year-old gymnast Gabby Douglas made America proud when she took home the gold at the 2012 Summer Games in London, but at her core, the go-getting teen is just a regular girl with a fondness for the undead cuties of The Vampire Diaries.

Paul Wesley, Ian Somerhalder, Michael Trevino and more cast members of the CW hit shot a special message for the high-achieving gymnast, giving their words of congrats (and a blown kiss or two) to the awestruck Olympian.

Watch the adorable moment above!

2. Jennie Garth on Her Dramatic Slim Down

In a new interview with ET Canada, Jennie Garth responds to reports of her dramatic post-breakup weight-loss.

"I've been certainly going through a transitional time in my life and I think anybody who has been through something like what I'm going through, and have been going through for the past couple years can definitely relate that your body changes with your emotional state of mind sometimes. I think a lot of women can relate to that," Garth says.

After splitting from estranged husband Peter Facinelli in March, photos of a seemingly skinnier Garth surfaced, causing some fans to worry about her.

The actress reassured that she is still focused on staying healthy, saying, "It's been summer, there's lots of fresh fruits and vegetables, we have so many fruits at our ranch where we've been living, so eating healthy, especially with three girls, body image is something that I try to set a good example for them. Everyone of my girls is a different size and shape and I want them to be comfortable in their own skin and be healthy minded as well as physically."

Garth and Facinelli cited "irreconcilable differences" as the reason for their split and requested joint legal and physical custody of their daughters: Luca, 14, Lola, 9, and Fiona, 5.

3. Sherman Hemsley Cause of Death Revealed

Authorities have released the cause of death for actor Sherman Hemsley, who died last month at age 74.

A statement from the coroner's office in El Paso, TX, states that Hemsley died from a complication of lung cancer known as Superior Vena Cava Syndrome. The illness is triggered by an obstruction that causes a narrowing or blockage of the second largest vein in the body.

The Golden Globe nominee -- perhaps best known for his role as George Jefferson -- passed away at his home in El Paso on July 24. Hemsley first broke into television in 1973, appearing on All in the Family, and his character's popularity earned him his own spinoff, The Jeffersons.

During its 10-year run, the program broke barriers as the first prim time show to star an upscale African-American couple. The show was also ahead of its time in casting the first interracial couple on a major sitcom.

4. New Whitney Houston Greatest Hits Album Out Soon

This fall, RCA Records is set to release the 'first authoritative greatest hits album' from Whitney Houston, according to Billboard.

The late singer's previous hits album, Whitney: The Greatest Hits, came out in 2000, but the news source reports that the latest set is expected to go more in-depth, spanning Houston's entire career.

Whitney: The Greatest Hits became this year's fourth biggest-selling album after Houston's death, selling 836,000 so far. The album has sold a cumulative 2.6 million copies in the U.S. since its debut.

The soundtrack to Houston's final film Sparkle, out August 17, has also been on Billboard's radar, selling 12,000 copies in its first week.

The new project will have plenty of choices, as Houston earned 39 hit singles on the Billboard Hot 100 over the span of her career -- 11 of which reached No. 1.

The exact release date of the upcoming album has yet to be announced.

5. Natalie & Benjamin Tie the Knot!

Congratulations to Natalie Portman and Benjamin Millepied!

According to Us Weekly, the 31-year-old Hollywood star and her 35-year-old French dancer/choreographer beau made it official in a Jewish ceremony at a private home near Big Sur in California last Saturday. The 8 p.m. wedding took place beneath a chuppah, in the dark.

A source told the magazine that Macaulay Culkin was among the 100 guests at the wedding.

Portman and Millepied were rumored to have married secretly back in February after they were spotted wearing bands on their ring fingers at the Academy Awards.

Back in December of 2010, Portman confirmed that she was not only engaged to, but pregnant with the child of her Black Swan choreographer and co-star, whom she met on the set of the film that earned her an Academy Award. The couple had their first child together in June of 2011: baby boy Aleph, who is named after the first letter of the Hebrew alphabet.

Prior to winning her Oscar, Portman memorably thanked Millepied during her Golden Globes acceptance speech, saying, "Benjamin choreographed the film, and also you might remember him in the movie as the guy when they ask, 'Would you sleep with that girl?' And he's like, 'Pffsh, no.' He's the best actor. It's not true: He totally wants to sleep with me!"
