Lauren Conrad Parties It Up with Ashlee and Pete

Enjoying the weekend with a summertime party, a handful of stars were spotted heading to a private fete in Los Angeles, California on Saturday (August 14).

With Lauren Conrad among the partakers, the former MTV reality star was joined by the always adorable trio of Ashlee Simpson, Pete Wentz and their son Bronx Mowgli.

Keeping busy since making their way back to the west coast, Ashlee, Pete and Bronx are fresh off of a family trip to New York City.

The former "Melrose Place" actress and her two main men made the east coast trip for Pete's concert duties, as Ashlee tweeted, “I love watching mr @petewentz play :) the show was so good last night! Songs are stuck in my head woop woop!”
