Britney Spears opens up to OK! magazine in a cover story for their new issue about her marriage to Kevin Federline and the impending birth of her second child. “This is a lot better than the first one,” she says of her current pregnancy. And the singer revealed that she’d like to have three “boo boos” in total, a reference to mishaps involving her baby son Sean Preston. Britney also dismissed the notion that K-Fed isn’t happy about their growing brood. At first, “he was a little shocked,” she admits, but shares that she and Kevin are now thoroughly excited about the welcome addition.
