The stars came out to see Long Island native Billy Joel perform at Hampton (Social) @ Ross Saturday night. On hand were two of his favorite ladies: ex-wife Christie Brinkley, with whom he remains on good terms, and their daughter, singer Alexa Ray Joel. See below:

We would never have guessed that Billy Joel's daughter would be a certifed cutie, but her mom is a supermodel, after all. We heart Alexa Ray Joel. Not just because she's pretty, either - it's nice to see a famous family that's not entirely dysfunctional!

The entire five-show summer concert series, in which mega-artists perform at the Hamptons' Ross School for small, intimate crowds, opened with Prince and closes with Tom Petty & the Heartbreakers. Tickets for the Billy Joel concert started in the thousands.

Also in attendance were talk show goddess Kelly Ripa and her hubby, Mark Consuelos, Mary-Kate Olsen and troubled 30 Rock star Alec Baldwin, among others.
