Kristen Stewart was denied entrance to a bar.

The 'Twilight' actress - who at 19 is two years shy of the legal drinking age in the US - attempted to get into the Ed Hardy Shoes Happy Hour event in Park City, Utah, on Saturday (23.01.10) but was denied entry by a bouncer.

An onlooker told America's OK magazine: "As they started walking in, the bouncer stopped them and asked for their IDs. When he informed Kirsten that she couldn't enter because she was underage, she and her friends seemed pretty surprised.

"Her friends tried to reason with the bouncer and told them that they just wanted to sit down and relax for 30 minutes but the bouncer still declined them. They huddled up for a few minutes, discussing what to do next and eventually left."

Kristen is currently in Utah for the Sundance Film Festival, where she is promoting 'The Runaways' alongside Dakota Fanning.
