Kellee (Talks about bonding with her onscreen sister Zoe Saldana): I feel like this is the sister that I never had. I actually just punk'd her though with Ashton Kutcher. I felt really bad because I had to lie to her for three weeks. But it went well. The punk went well. She was a trooper; she was so great. But we did, we became great friends. We spent time at each other's house. We both know each other's family. She's a wonderful person and she is like the sister that I never had.
