Crystal Harris, who called off her wedding to Playboy founder Hugh Hefner, 85, just days before they were set to tie the knot Saturday, kept close company with the reality star this weekend in Las Vegas, where she attended a pool party.
Trading her Romona Keveza wedding gown for a leopard print cover-up, this month’s Playboy cover girl, 25, partied with Montag, 24, at Sin City’s Wet Republic on Saturday.
Bikini-clad, the two hung out poolside, flipping through Harris’ Playboy spread.
“I’m doing okay,” Harris said at the bash. “I just had to get away.”
