Yesterday at Comic-Con it was announced that Michael Keaton will be voicing the character of Ken, Barbie’s long-time boyfriend, in Toy Story 3 when it comes out in summer of 2010.

Director Lee Unkrich said that, “Barbie is back, and this time she plays a bigger role. So naturally we had to bring in her companion Ken this time. And we can announce today that he’s voiced by Michael Keaton. He worked with us on Cars, where he voiced the bad guy, and he was a blast to work with so we invited him back as Ken.”

In what looks set to be a DVD extra, they also made a Groovin’ with Ken faux-interview where the iconic doll discusses accusations that he’s a girl’s toy (“Who said that?!”) and responds to the suggestion that his girlfriend is a bigger star.
