Katie Holmes is the latest high-profile celebrity to finally join the ranks of the tweeting world, and it’s this kind of star power that the company hopes will bolster its image as it prepare for an IPO. In about 6 hours on the service, Holmes has already racked up nearly 16,000 followers.

Holmes used her first tweet to publicize a cast photo from the set of her current filming project, an adaptation of the Newbery award-winning children’s classic The Giver.
