NEW YORK —  Britney Spears (search) and Kevin Federline (search) were everywhere Tuesday — including reading a top 10 list on CBS' "The Late Show with David Letterman."

On the day their reality show premiered on UPN, the 23-year-old pop star and her husband stopped by Ellen DeGeneres' (search) syndicated talk show, and later paid Letterman a visit.

"Britney and Kevin: Chaotic" also premiered — a six-episode series featuring private home videos during their courtship, engagement and wedding.
