"America's Got Talent" has added a FOURTH JUDGE for its upcoming season:  HEIDI KLUM.  She'll join returning judges HOWARD STERN and HOWIE MANDEL, along with MEL B from the SPICE GIRLS, who's replacing SHARON OSBOURNE

Sources say that SETH MACFARLANE and CHARLIZE THERON hit it off at the Oscars, and may have a budding relationship going.

CHARLIE SHEEN thinks he can save LINDSAY LOHAN.  He says, quote, "She can continue to hang out with her dress shredding club buddies, or turn to me for some advice from a guy who's been down the road as well as every other side trail on the journey.  If she listens, she'll win.  If she doesn't, that's on her." 

Well, here we go again:  "Two high-level industry sources" tell the "Hollywood Reporter" that NBC is "moving forward" with a plan to give "The Tonight Show" to JIMMY FALLON when JAY LENO'S contract is up next year.  Supposedly, they'll announce it in May.  But for now, NBC is denying it, and Leno's rep won't comment.

On the PBS series "Finding Your Roots", KEVIN BACON and his wife KYRA SEDGWICK found out that they're 9th cousins once removed.  Kevin is also distantly related to BRAD PITT and PRESIDENT OBAMA.   But is that new info?  I don’t think so, there is even a game to prove everyone is connected to Kevin Bacon with less than six degrees of separation… or six degrees of Kevin Bacon!
