Justin Timberlake, who married Jessica Biel over the weekend, debuted a new song at their wedding.

+ Justin Timberlake premiered a new song (YAY) -- but only his wedding attendees got to hear it (boo). C'mon JT, we want to hear your new jam, too. Maybe active tweeter Questlove, who reportedly served as wedding DJ, will tweet the track. (MTV News)

+ So much for Katy Perry taking a break (and we're not complaining). She's booked to perform at President Obama's re-election event, "America Forward," tomorrow in Las Vegas. (MTV News)

+ Check out One Direction singing a lovely acoustic version of "Live While We're Young." (Just Jared Jr.)

+ Watch Lil Wayne sing "Take Me Out To The Ballgame" during Game 7 of MLB's National League Championship Series last night. He rooted for the San Francisco Giants, and incidentally, they won. (Billboard)

+ Listen to Cee Lo Green's collabo with The Muppets for "All I Need Is Love," which they performed in Las Vegas for a Christmas special with Rod Stewart and Eric Benét. The song appears on Cee Lo's Magic Moment, due Oct. 30. (Rap-Up)
