Lauren Bush & David Lauren's Posh Engagement Party

Lauren Bush and her fiance David Lauren celebrated their engagement with a swanky party in the Hamptons last weekend.

The all-white soiree was hosted at Hearst heiress Anne Hearst‘s farm in Water Mill, New York where guests like David’s designing dad Ralph Lauren and Paris Hilton‘s parents Rick and Kathy sipped on cocktails before enjoying a nice dinner.

If that’s what went down at the engagement party, we can only imagine the wedding!
