‘Extra' Exclusive: Britney Spears on Her Charity Ride, Meeting Hillary Clinton & That Viral Wardrobe Malfunction

The charity ride is part of her effort to raise $1 million for the cause. “I'm all about kids,” Britney said. "I was like, 'This is something I have to do.' They came to the show the other night, they're absolutely adorable, it's been nice, it's been very cool.”

Mario also took part in the ride, with Britney putting together the music and working closely with the foundation's president, Jeff Gordon. He gushed about her $200,000 donation to the foundation, saying, "Britney has made it all possible... and the kids adore Britney. I wish the world got to see that what she has done — she has taken it to a whole new level.”

To top it all off, Britney is giving one dollar of every ticket from her Piece of Me” show to the foundation as well. Find out how you can help at Nvccf.org!

Along with giving back to the world, the pop princess also chatted about meeting Hillary Clinton, who was campaigning in Las Vegas. As for why she's a fan of Clinton, Spears shared, “I love the fact that she's a great communicator with people and she's very present and aware.” The two even bonded over their love of food. Spears shared, “We talked about food a lot. We talked about jambalaya, we talked about our favorite restaurants here in Las Vegas. She's a great lady.”

Spears, a single lady, also dished about her love life, saying there was "no one special” at the moment.

Britney also commented on her too-hot-for-TV moment while singing “I Love Rock 'n' Roll” during her hit Vegas show, where her top nearly came off. “Yeah, well, it was really tight around my neck. It was the second time I've worn it and I was on the guitar and it just popped and I was like, 'Oh, my God. It's never done that before!' so I just had to hold myself. One of my dancers, Zach, he came to me and put a shirt on me, so I had, like, a huge nightgown onstage… it was kind of invigorating!”

Though she covered up onstage for a hot second, the 34-year-old is not afraid to show off her insane body on social media, looking better than ever. As for how she stays fit, she said, “I like to work out. I have a trainer. I love swimming.”

Along with those bikini pics, Britney also loves sharing snaps of her boys Jayden and Preston. “I have to ask permission. They're very funny [about] what I put out. Like, 'Mom, we want this on Instagram. Mom, this cannot go on Instagram.'”

Since Halloween is only days away, what will her sons' costumes be? She shared, “Preston's gonna be a clown. Jaden's gonna be a statue of a pumpkin.”
