Fans may be focusing on Cameron Diaz? red-hot romance with baseball player Alex Rodriguez, but her Bad Teacher co-star, Molly Shannon, can?t say enough about her pal?s on-screen skills. ?She?s a real pro, and I really look up to her. She?s going to kill it in this movie, and she?s the perfect person to play the bad teacher,? Molly, who is partnering with Centrum to find America?s Most Amazingly Energized Woman this holiday season, tells In Touch. The actresses bonded on the LA set of the comedy, also starring Cameron?s ex Justin Timberlake, earlier this year. ?She has a great sense of humor, she?s just a blast! We hung out and talked a lot and laughed. She?s a real girl?s girl,? Molly adds. The Saturday Night Live alum is currently working with another blonde, theater darling Kristin Chenoweth, on Broadway in Promises, Promises. ?I?m having the time of my life!? she says.
