Runaway Bride Crystal Harris spent her would-be wedding day on Saturday partying it up in Vegas with none other than Heidi Montag. Really?? Heidi Montag of all people???
Hef's ex said she "wanted to get away from L.A." so that she "didn't have to think about the wedding."
Crystal was seen wearing a skimpy black bikini while spending time by the MGM pool Wet Republic, looking at her Playboy spread and laughing it up with Heidi.
Meanwhile, when Hef's other ex Holly Madison saw the photos of Crystal partying in Sin City, she lashed out at the playmate, tweeeting:
"That's a new low.
Trust me, NO ONE is interested in filming Crystal! She left Lifetime high and dry while filming a two hour special." (referring to her wedding special with Hef.)
She also called her "disgusting" and said "whoever booked her is tacky."
Holly totally went there! And we don't blame her! It's definitely tacky to be seen partying on the day you were supposed to get married!
Whose side are U on? Crystal? Holly? Hef?
