(Cover) - EN Showbiz - Tom Cruise is apparently doing a lot of soul-searching to figure out why his marriage to Katie Holmes ended.

The actor was blindsided when his wife of five years filed for divorce last month but the pair have come to a very quick settlement.

Sources have told People magazine that Tom "was thinking, What did I not see?'" as he deals with the fallout of the high-profile breakup.

He is said to have found it especially hard being away from six-year-old daughter Suri but had commitments before finally reuniting with her on Tuesday after a month apart.

"He's wanted to see her as fast as possible since this started," an insider said. "He couldn't shut down production [on Oblivion], cost people their jobs. People count on him."

Meanwhile, although Tom's divorce from Katie is not finalised yet there is already speculation on who is going to be Mrs. Cruise Number Four.

"Tom's next marriage will be inside the church," Scientology expert Margery Wakefield told The Enquirer.

Insiders have predicted that 27-year-old Latin beauty Yolanda Pecoraro would be a good fit for Tom because they have dated in the past and she is a devout Scientologist. (C) Cover Media
