'90210' star AnnaLynne McCord spent her Easter weekend poolside in Las Vegas at a friend's Wet Republic bachelorette party.

According to OK! Magazine, McCord, 23, and her sister Angel were on hand Saturday afternoon to celebrate ex-boyfriend Kellan Lutz's future sister-in-law Sara Oriolo. Oriolo is engaged to the 'Twilight' star's brother, Brandon.

"Hello everybody, I want to introduce the future Mrs. Lutz. I'm very, very excited about her big day next week. Say congratulations to Sara everybody," McCord told the Wet Republic crowd. "Thank you guys so much, have fun, swim, drink, get drunk."

McCord and Lutz, who were plagued by breakup rumors during the course of their almost two-year relationship, split up last November.
