Entertainment Tonight

From her headline-grabbing break-ups with Justin Timberlake and former husband Kevin Federline, to constantly being surrounded by paparazzi -- Britney Spears is telling all in a new documentary!

The all-access pass into Britney's fascinating life also includes an interview with Britney's famous pal Madonna!

In her MTV documentary that aired Sunday night entitled "Britney: For the Record," the singer let everyone in on what it's like to be one of the most famous women in the world.

On Family & Children:

"At this point I have two precious jewels, my two boys...and my job," Britney said of her sons Sean Preston and Jayden James. "Those two things have kept me going really strong for the past three years."

Britney unveiled the fun-loving relationship she has with her father, Jamie Spears. The doc shows Jamie affectionately calling Britney "my baby," and cooking her cheese grits for breakfast before her appearance at the 2008 MTV Video Music Awards. Britney's father was also moved to tears during her video shoot for "Womanizer," and again when Britney did a funny impersonation of him.

The pop megastar also took viewers inside trick-or-treating on Halloween night with her family, as her sons dressed up as a lion and a turtle.

Madonna's Interview:

Madonna also appeared in the documentary, revealing how she identifies with Britney. "There's a certain fragility about her and vulnerability about her that makes me feel maternal towards her," Madonna said. "There are aspects about her that I recognize in myself when I first started out in my career. I also admire her talent as an artist."

On Relationships:

"With Justin, he was a part of the magnitude of what I'd become," Britney revealed. "So then when he was gone, I was like, 'what am I supposed to do with myself?'"

Britney said she was devastated by her break-up with Justin, but handled it better than her divorce from Kevin.

"With Kevin -- because I had two children with him -- I did not know what to do with myself," Britney said. "I built my dream home in Malibu, a huge house and the pool and the huge yard for the kids, and I did everything for them."

On the past 3 years:

"It was just a really, a really bad time in my life," the singer confessed. "And, it's crazy." Britney goes on to say she's grown up over the past few years and she is now more careful on who she lets into her life.

"My trust has really been battered...," she said. "I'm very wary of a lot of things."

Overall, Britney said she wants people to know that she is just like everybody else, adding, "I love what I do -- I love my babies, and I work really hard."
