Robert Downey Jr.'s birthday karaoke
Robert Downey Jr. sang for guests at his 50th birthday party.
The 'Iron Man' star was treated to a performance from 'Hungry Like The Wolf' hitmakers Duran Duran before joining jazz rock band Steely Dan on the stage to belt out 'Reelin' in the Years'.
He said: "It was kind of a big deal. What occurred was I had two bands. I had Duran Duran play and then they opened for Steely Dan. I was stoked.
"They said, 'Come up and sing "Reelin' in the Years" because we saw you sing that at a show once,' and I was like (shakes his head)."
However, things didn't go as well for Robert as he hoped because he found himself getting a bad case of stage fright.
Speaking on The Late Late Show with David Letterman Show, he added: "I forgot the words because I was a little excited to be up on stage with Steely Dan."
When asked if he froze, he added: "No, I kind of lip-synced it to nothing."
Meanwhile, Robert previously admitted reaching the milestone had made him feel more "reflective and grateful".
He said: "I was really just more reflective and grateful. I got to be around all my loved ones, friends and co-workers."
