Britney Spears and Kevin Federline have spoken about their marriage on the Ellen DeGeneres chat show.

The expectant parents chatted about their life together, with Kevin revealing how much he loves being with Britney - especially the arguments.

"The make-ups from the arguments are the best part. Married or not, I love being with her and she's fun," he cooed.

"She's very sweet...You can't be serious all the time. Life's too short to be serious all the time."

Speaking about his new found fame and the persistence of the paparazzi, Kev added: "I wouldn't say it's completely hard.

It gets on you sometimes. It has its ups and downs but I'm just happy with who I'm with. I love her and everything else is whatever."

Ellen ended the interview by joking about becoming their baby's godmother...mind you, on the strength of her pre-birth presents, she could be in the running.

Ellen concluded the interview by handing over a "pimped-out" Silver Cross pram, complete with spinning chrome wheels, neon lights and a Sony DVD player.

She also handed over nappies with "Oops... I did it again" printed on them, as well as some specially designed baseball hats to help the new family avoid the media.

Britney's said "I'm not Britney Spears", whilst Kevin's read "I'm not Kevin Federline", and a weeny one for the baby was printed with "I'm not their baby."
