NEW YORK (AP) -- Britney Spears, expecting baby No. 2, says she and husband Kevin Federline didn't plan the pregnancy. "It just kind of happened," the 24-year-old singer reveals in an interview in the latest issue of People magazine, on newsstands Friday.
She adds, laughing: "I'm going to wait a while for the next (one)!"
At eight months pregnant, Spears is mom to 11-month old son Sean Preston, the couple's first child. "I feel like I've been pregnant for 10 years!" she says.
Having back-to-back babies can be stressful, she says, but she adhere's to her mom's advice to take it "one day at a time."
"It is now starting to get a little tiring, holding (Sean Preston), but the whole pregnancy I've done it a lot because he's very attached," she tells the magazine. "It makes me feel needed and wanted, so I like it too."
Spears says she and Federline, 28, don't know the gender of their baby-to-be. The little one and its big brother "are going to be so close together, it's going to be weird. But I love it," she says.
Spears - who has gained about 40 pounds during her pregnancy - plans to hit the gym and begin dieting soon after having the baby, scheduled to be a Caesarean birth, as was her first. She is not, though, ignoring her cravings at this point.
"Crunching ice and chocolate, oh my God," she says. "I'll get up in the middle of the night and I'll get a Hershey's bar, the real big ones, and I'll put it in the microwave and melt it and eat it. It sounds disgusting, but it's so satisfying."
With the constant media buzz surrounding Britney Spears (the good, the bad, and the down right embarrassing), one wonders what goes on in Brit's mind every time the pop star steps foot outside to face the paparazzi. Now, for the first time, TMZ has the inside scoop on what Britney may be thinking
Sources working at a recording studio where Britney was working Friday told TMZ that as she walked to her car in this video, the singer told herself- out loud- "Please don't trip! Please don't trip! Please don't trip!"
