Britney Spears talks about her life in Vegas as she covers for Billboard Magazine

The 33-year-older American singer and actress is the cover celeb for Billboard Mag for the first time, as she discussed issues surrounding her Piece Of Me residency, which is expected to be extended through 2017, and “slowly but surely” working on her upcoming ninth studio album…which she isn't too fussed about at the moment.

Here are five things Britney Spears told Billboard magazine about her home away from home.

1. Her new boyfriend, Charlie Ebersol, is a frequent visitor.

"Oh, he loves it. He comes every weekend, even though he's flying all over the place," says Spears. "It's always really nice when he comes. The kids love to see him. It's great." What do she and Ebersol, 32, have most in common? "I feel like our passion for life is pretty much on the same page."

2. So are her sons, Jayden James and Sean Preston.

Spears keeps a residential suite three nights a week during show weeks just a few blocks away from Planet Hollywood, where her kids visit every other weekend. "It's really big, kind of like a big condo. It's four bedrooms. We have a yard, it's really nice," she says.

3. Where does Britney go offstage? Think sushi and Sonic -- not the slots.

Not one to hit the tables ("I'm not a gambler at all, that's not something that I'm into at all"), Spears instead gets amped when talking about her favorite places to eat. "Oh my God, I love Sushi Samba, I love Koi. Those are my two favorite sushi places. I could literally go there every day of my life." And then there's her guilty pleasure, Sonic, which has a Strip-adjacent location right off Flamingo Boulevard. "They have Southern sweet tea and everything from Louisiana, so that's really nice." Spears pauses to consider her dining habits. "Actually, I need to start eating at more places this year. I stick to my two restaurants and I need to branch out a little bit."

4. A slumber party at Celine Dion's house inspired her to come to Vegas.

Shortly after wrapping her Dream Within A Dream Tour in 2003, Spears flew out to Vegas to check out Celine Dion's A New Day… residency. "I remember coming here, and I stayed with a friend at her house, and I remember how beautiful it was," Spears recalls. "Just the set-up and everything was just really cool, low-key, and her dressing room was great. I was actually jealous, like, "Oh my gosh, she gets to be in one place all the time.' And I just thought, ever since then, that everything really clicked."

5.) "Toxic" is her favorite song to sing during Piece of Me.

"I get rained on and it wakes me up," Spears says with a giggle, noting that 90-minute sets three nights a week can be grueling. "And I'm able to really give more because I've just had this shower onstage. It's actually really fun, I jump off of a tree and it's kind of exciting."
