It must have gotten really bad for Katie Holmes.

She didn’t even wait for “Rock of Ages” to get out of the theaters before she filed for divorce from Tom Cruise in New York Thursday â€" and in Hollywood marriages, promotion is everything.

Katie has been blinking out hostage messages for some time. For months, the 33-year-old actress been spotted with daughter Suri at the FAO Schwartz toy store or on the sidewalk near her apartment in bland clothing, unsmiling. Holmesgirl almost never smiles more than a Mona Lisa closemouthed curve â€" go ahead and Google her.

Suri is 6 years old, the exact age Connor Cruise was when reports of religious differences surfaced between his father and Nicole Kidman over how he and his sister Isabella would be raised.

“I’m a Catholic girl,” Kidman said at the time. “It will always stay with you.”

Holmes attended an all-girl Catholic school in Ohio for 12 years. Perhaps Cruise objected to some of her beliefs; perhaps she did not want Suri studying L. Ron Hubbard’s Scientology tenet that says 75 million years ago galactic dictator Xenu brought aliens to earth.

Unless Holmes nobly refuses to sign a gag order and goes on to write her memoir â€" as she has said she’s wanted to do in the past â€" we may never know exactly what went wrong.

Katie may have actually been in love with Tom when they married in a lavish ceremony in Italy in 2006. Or, she may have been in love with his $275 million. Or the “Mission Impossible” star’s unmatched Hollywood power.

But the marriage didn’t help her career at all. In 2005, she made $1 million for playing Rachel Dawes in “Batman Begins.”

By the next year, she had become Mrs. Tom Cruise and the biggest role she’s landed since was as Jackie Kennedy in a quickly cancelled TV series. She wasn’t even invited back to do the next Batman, “The Dark Knight,” released in 2008.

To outsiders, their union felt stilted, arranged. The couple’s body language told a story of a pair of actors posing.

Nicole lasted 11 years with the enigmatic actor, who’ll turn 50 on Tuesday. Katie didn’t last half that.

Maybe Katie just couldn’t take the Cruise control.
