Wearing a loose, pink-and-beige dress, Spears only slightly showed signs of her pregnancy, which she announced in early April. The 23-year-old pop star said that it was she that popped the question to Federline — who didn't even go for it right away.
"Actually, I was a little rejected at first. I kind of got slapped down," Spears said on the syndicated morning talk show. She and Federline, a 27-year-old former backup dancer, married last September.
"I told her that it's not right for the woman to ask the man. The man's supposed to get on one knee and do it right," Federline said. "It took me about five minutes, and then I turned around and asked her."
Of course, the couple will be getting plenty of airtime in the UPN reality show, "Britney and Kevin: Chaotic (search)," set to premiere Tuesday. The six-episode series features private home videos during their courtship, engagement and wedding.
MTV (search) announced Tuesday that the network will re-air the shows on Thursdays, beginning May 26 (10 p.m. ET).
While the exposure is nothing new for Spears, being front and center is a different experience for Federline, who says the publicity and paparazzi-hounding are only minor distractions.
"I'm just happy with who I'm with. I love her and everything else is whatever."
