Former "The Hills" star Audrina Patridge had fun in the sun at Foxwoods Resort Casino's "Liquid Sundays" pool party over the weekend.

The reality star wore a sexy black and white bikini with a silver cross necklace.

Patridge spent time with her friends while hanging out at the Connecticut casino. She drank Crown Royal and ate fruit, signed autographs, posed for photos and danced with fans.

Earlier this year, the star celebrated her 27th birthday with a pool party in Las Vegas.
