Tom Cruise and Katie Holmes want another daughter.

The couple is reportedly trying for another baby and would love it to be a little sister for 18-month-old daughter Suri.

A source on the set of Tom's latest movie 'Valkyrie' said: "It's something they want to do sooner rather than later. Suri has been such a joy for Tom, so he'd be more than happy to have another girl. Katie feels the same."

The couple is staying in Berlin, Germany, while Tom films the World War II drama, and the 45-year-old actor has signed up to star in 'The Hardy Men' as soon as 'Valkyrie' wraps next month.

Katie, 28, is keeping her schedule free and has no new movies lined up. A source told America's OK! magazine: "She is preparing for another pregnancy."

Asked recently if she wanted more children, Katie said: "Yes, definitely. We're having the best time, it's so amazing. We have so many kids in our house, there's always this wonderful chatter and this great noise of kids."

Katie and Tom live in Los Angeles with Suri and Tom's two adopted children, Isabella, 14, and Connor, 12, from his previous marriage to Nicole Kidman.
