How did 90210's AnnaLynne McCord celebrate 9/02/10? By having dinner with castmates Shenae Grimes and Jessica Stroup at XIV Restaurant in LA — and spilling about Kim, Khloé and Kourtney Kardashian's cameos on the third-season premiere of The CW hit! "They're such sweethearts, and I love sisters doing sister things," AnnaLynne tells In Touch. "I really love that they do everything together." AnnaLynne, who's been lobbying to get her own sisters Rachel and Angel on the show, was the only cast member who got to share a scene with the Kardashians. "We have a little moment where they come in and they bring some of the clothes from the store. They brought in their label, they got their name in there, and they got the store in there. They're smart businesswomen." AnnaLynne says that the Kardashian sisters were total pros. "They were very quiet — I think that they just wanted to make sure that they did a good job. Kim was adorable. She was so cute, and I wanted to squeeze her! Toward the end, we were joking about sister stuff. Khloé was so cute. She was like, 'Yeah, I don't really tell Kim that [Keeping Up With the Kardashians] is really my show!' I was like, 'I love it!' It was really fun working with them."
