Britney popped the question

Ellen DeGeneres (C) surprises parents-to-be Britney Spears (L) and her husband Kevin Federline with a specially made customized Silver Cross Pram with neon lights, spinners and a Sony DVD player.

A pregnant Britney Spears appeared with husband Kevin Federline on Ellen DeGeneres' television show - the first TV interview for the couple together.

Wearing a loose, pink-and-beige dress, Spears showed only slight signs of her pregnancy, which she announced in early April. The 23-year-old pop star said that it was she who popped the question to Federline.

"Actually, I was a little rejected at first. I kind of got slapped down," Spears said.
