As usual Playboy was on hand after Lollapalooza to throw the ultimate Lolla after-party, hosted by Playmates Crystal McCahill, Summer Altice and Sasha Bonilova. Hundreds of guests packed on board the midnight yacht cruise to get down with DJ Chuckie on Lake Michigan after a stormy-but-worth-it night of live tunes. The party was so bangin' that our Playmate of the Year Claire Sinclair had to make a surprise appearance. And we're glad she did.
