TMZ reports that the 20-year old actress was trying to get into a restricted area to meet up with her friends when security spotted the phony ID and called the authorities last Thursday night. Many celebrities had shown up to the Indio festival grounds early for parties before Coachella's first weekend officially kicked off on Friday.
According to the gossip site, Berglund was eventually released with only a citation. The actress was spotted at the Paper Magazine party on Friday night.
Coachella continues for a second weekend beginning on Friday with headliners Guns N' Roses, LCD Soundsystem and more.
