Late Show

Lauren was spotted taping at the Late Show with David Letterman on Thursday, April 23. Here's a bit of what went down.

Background: Lauren Conrad was invited to Heidi Montag and Spencer Pratt's weekend wedding, but she's not going. Maybe you can. She joked with David Letterman that "My ticket is currently on eBay, so...." The designer -- who ended her run on The Hills earlier this year -- says she won't sue Pratt for starting rumors that she starred in a sex tape. The lie ruined her friendship with Montag, who sided with her soon-to-be husband. "He would enjoy the publicity," Conrad says. Letterman admitted he was bummed the tape was a fake. "Sorry, I kind of wanted to see it," he told Conrad.The Late Night host also called Pratt "creepy." "The beard doesn't help," Conrad said. "He's not super nice," she continued.

p.s. I totally looked on ebay and the invite isn't there, too bad. I bet Lauren could make money off of it.
