Kathie Lee Gifford and Hoda Kotb brought a Latin flavor to 'Today' (weekdays, 7AM on NBC), interviewing rapper and producer Pitbull and dancer-cising with Zumba creator Beto Perez. They talked with Pitbull, co-founder of the Bad Boy Latino label with P-Diddy, about the finer points of creating mega-hit records before putting on their workout clothes and trying to keep up with Perez in an outdoor exercise session.

Pitbull has appeared on a lot of other artists' records, including Marc Anthony and Lil' Jon. Sometimes he writes the entire record, sometimes just his part, and he said he was thankful that big names seek him out. "I don't look at it like they're clamoring to get me on the record, I look at it more like they gave me an amazing opportunity after all these years of hard work," he said. "To me, the secret behind a record is arranging the record and having fun while you're doing it."

P Diddy (billed under his real name, Sean Combs) played action star last night on 'Hawaii Five-0' (Monday, 10PM on CBS), appearing as Reggie Cole, a New York detective investigating the murder of his wife. In the episode, Cole is trying to protect his son while on the run, operating under cover for the FBI. He is undercover in Hawaii, where a suspect in the murder of Cole's wife winds up dead, and Cole becomes a suspect.

McGarrett asks Cole to turn himself in, but he refuses, claiming innocence. "I can't do that," says Cole. "I only have one chance to find out how this went down." Cole tries to stay ahead of the 5-0 task force by monitoring a portable radio he steals from a squad car.

Them's fightin' words: 'Glee' creator Ryan Murphy and Kings of Leon drummer Nathan Followill got into a war of words today after Murphy made like Cee Lo and said "Forget you" (the unedited version) to the band for not allowing 'Glee' to use their music on the show.

"Dear Ryan Murphy, let it go. See a therapist, get a manicure, buy a new bra," tweeted the drummer, according to Vulture.

Murphy responded via statement to Perez Hilton, saying "Wow. That's a homophobe badly in need of some education." Followill later apologized.
