The gorgeous ’90210′ star AnnaLynne McCord got all gussied up in Las Vegas this weekend when she hosted a celebration for her sister Rachel‘s 21st birthday at Pure Nightclub. The third McCord sister Angel was also in attendance. The three lovely ladies dressed in the frou frou style of french Versailles, similar to Marie Antoinette.  Recently, AnnaLynne admitted that her relationship to Dominic Purcell can be difficult while he films ‘Vikingdom’ in Malaysia.

“Right now it sucks,” McCord told Us Weekly. “I keep getting pictures of him in all his Viking outfits, and I’m like, ‘Are you just trying to tease me?’ He just left a week ago and it feels like a month or a year.”
