Lauren Bush and David Lauren celebrated their engagement last Saturday with an all-white themed engagement party in the Hamptons. The party of the granddaughter of former president George H.W. Bush and niece of former president George W. Bush and the son of designer Ralph Lauren was hosted by Hearst heiress Anne Hearst and her husband, Jay McInerney. Guests were all the Laurens, Rick and Kathy Hilton - parents of Paris and Nicky -, Lauren's mother Sharon Bush, and designers Cynthia Rowley and Douglas Hannant. The guests enjoyed cocktails, dinner and speeches by Sharon Bush and Rick Hilton.

The wedding will take place at the Colorado ranch of the Lauren family. Lauren's grandfather, George H.W. Bush is expected to attend. With so much 'Lauren' going on, what will Lauren Bush do with her surname? Stay Lauren Bush, become Lauren Lauren? "I think that it will be Lauren Bush-Lauren," she told People Magazine in April. "That's not final, but I think it's nice to have the same name as your husband. I am sort of old-fashioned that way." Whereas the name might change, choosing a wedding dress designer is a no-brainer, her future father-in-law, Ralph Lauren, will create a dress.
