"I would be lying if I didn't say it was tough," says Federline about being Mr. Spears, "I think the expectation is real high for me you know, it's like you see my wife here she is this huge superstar everybody loves her, all of her music is just hits after hits and it's hard to compete."

Even though Kevin Federline hopes his new single "Lose Control" will be the next "Toxic," the musician claims no rivalry exists at home. "I don't see it as a competition you know? Maybe other people are putting it in that perspective, but to me it's not a competition ... I just have fun. I love rapping and making music period."

Kevin Federline also told Ellen DeGeneres that wife Britney Spears's cravings are "not too bad" compared to a year ago, before the birth of son Sean Preston.

"Ice chips all the time," he said about Spears's favorite snack – admitting that he had to ask his mother what that was all about, and she couldn't adequately explain it to him, either.

What he does understand, however, is that at age 28 he likes being a young father reports People Magazine.

"My father was young with me," says Federline, who, besides Sean Preston, is also dad to daughter, Kori, 4, and son Kaleb, 2 (their mother is actress Shar Jackson). "He was, like, 22. I had a good relationship with my father. He was able to keep up with me."

He also swore to DeGeneres that he does not know the gender of his and Spears's soon-to-be arrival.
