Jeremy Renner mixes up his sleeping pill with Viagra

On Jeremy Renner’s recent flight from Los Angeles to London, The Bourne Legacy star’s attempt to catch some shut-eye up in their air resulted in some problems below the belt.

“I had to get off the plane to go to work, so I had to sleep on the plane,” Renner, 41, recalled on Tuesday’s Jimmy Kimmel Live! “So I take a little sleeping pill, pop it and realize nothing’s happening – but something else was happening.”

What he thought was Ambien was actually Viagra, given to him by a friend.

“Not only did I not sleep the entire flight,” he added of his 10-to 12-hour trip, but he also had to deal with his pants “camping.”
