Buzz Bites (2/23/10): Bieber Covers Timberlake, Annie Lennox Loves Gaga

+ Yesterday, we showed you photos of Justin Bieber's performance at the Long Island tween-rock summit, Pop-Con. Today, we've got some video of J.B. paying tribute to the soul men who came before him. Check out Bieber covering Usher's "U Got It Bad" and Justin Timberlake's "Cry Me A River." (Oh No They Didn't!)

+ Speaking of paying tribute, it's called "mutual admiration" for a reason. In this case, it's a veteran paying homage to a newcomer. Annie Lennox recently took to her blog to write a post called "Ga Ga Ga Ga Ga." Guess who she was writing about? Yep, seems the Eurythmics singer is infatuated with all-things Gaga, from the tunes to the costumes to the set design of her live show. (Spinner)

+ After playing Friday Night With Jonathan Ross in England last week, Jay-Z brought things back stateside to kick off his Blueprint 3 tour in Florida. Check out picks of Hova, Trey Songz and Beyonce in action. (Rap-Up)

+ Never let it be said that Ludacris is the type of guy to kick a man when he's down—unless that man is Tiger Woods. Luda's new song, "Sexting," apparently begins with a sure-to-be-popular-at-the-Woods-residence parody of Tiger's recent "problems." Oy va voy. (Idolator)

+ Love the "island-pop" of Iyaz's "Replay"? Then take a sec to learn all about the rising star in this revealing interview, which discusses how Iyaz blew off Sean Kingston, his time at the New England of Technology, and much more. (PopEater)
