During the outing, Heidi and Crystal took turns on the arrivals carpet before heading to a VIP bungalow - with Miss Montag changing into a skimpy bikini as she joined revelers while tossing back a little champagne.

As previously reported by GossipCenter, Miss Harris called off her wedding to Hefner a few days back - as she told press, “It was mutual between Hef and I. There was no fight, we sat down and we talked about it.” She added, "For a while I’ve been having second thoughts about everything. I haven’t really been at peace with myself lately. I didn’t think it was really fair to him.”
