Paris Hilton dressed in green to celebrate St. Patrick's Day (and her cousin's birthday) on Monday, March 17.

The famous blonde joined her cousins, Whitney Davis and Farrah Brittany, at the Chateau Marmont in West Hollywood for Davis' birthday. While her cousins dressed in conservative black, Hilton couldn't hide her St. Paddy's Day spirit in a kelly green ensemble.

The heiress shared a photo of the three of them on her Instagram account, writing, "Celebrating @Whittles99's Birthday with @FarrahBritt. I love my beautiful cousins!"

It looks like Hilton has found someone else to celebrate, after extending her own birthday celebration for weeks on end. Of course, not being the center of attention didn't mean Hilton couldn't take a little time for herself ... well, her selfie.
