Katie Holmes and Tom Cruise are set to go on a trial separation. Reports say that the former "Dawson's Creek" actress wants to break away from Tom for a while.

Holmes, 29, is said to take her daughter Suri with her to New York, but Cruise would have none of it.

The actress is said to be "trying to break away from her controlled life under the watchful eyes of her husband and move to Manhattan in what will be a sort of trial separation."

Star magazine has quoted a source saying, "She desperately needs to be on her own for a while, but there's no way Tom is going to let her take Suri away."

"There's no way he'll allow it. He just doesn't want Katie - or Suri - out of his sight for long. He told her that if she goes to New York, fine, but he goes with her."

The magazine also adds that the "Top Gun" actor has the power over their daughter, who will turn two on Friday.

An insider says, "Tom wants to call all the shots when it comes to Suri. He has a lot of rules, and there's conflict."
