Did anyone catch Diana Ross’ appearance on Letterman last night? She was there to promote her new album, I Love You, and was asked about Dreamgirls. Dreamgirls is loosely based on her life and The Supremes. When asked if she had seen the film, Ross said no, but that she was “going to see it with [her] lawyers.” Even though it was a joke, you have to wonder if she is upset with the movie. After that, she did praise Beyoncé saying she is very talented and beautiful. “I like to inspire the talent that it is out there today,” Ross said. Look for her to appear on “American Idol” later this season.
