Justin Timberlake turned stand-up comedian on Wednesday (16Jul08) night when he hosted the ESPY Awards - mocking his celebrity friends and poking fun at his controversial duet with Janet Jackson at the 2004 Super Bowl.
The sports-loving star took to the stage in Los Angeles for U.S. TV network ESPN's Excellence in Sports Performance Yearly Awards ceremony.
Timberlake scored laughs with a comic performance in new movie The Love Guru - and tried out his act with a live audience at the event, picking on audience member Jessica Simpson and her American footballer boyfriend Tony Romo.
After giving them the nicknames RoJo and Tessica, Timberlake then recalled his infamous "wardrobe malfunction" with the breast-flashing Jackson four years ago.
He told the audience, "I wanted to be the only guy at a football game to get to second base."
Timberlake's on-stage antics can be seen when the awards show is aired in the U.S. on Sunday (20Jul08).
