Looks like Katie Holmes has ditched her Mercedes for something a little bit more compact ... a new, silver Mini Cooper!

Ms. Holmes, who is gearing up for the release of her scary flick Don't Be Afraid of the Dark, has been working hard to maintain her slim physique. Gotta get ready for all that press she'll be doing for her movie due out in August!

Now, let's talk about that car. With Tom Cruise's wifey able to choose just about any car she desires, we find this to be an interesting choice. Maybe Suri wanted mommy to get something that looked like a toy car. Cute!
