The TomKat rumors rage on.

The subject? Fidelity. While the Tom's away, will the Katie play, so to speak? That's the question surrounding the mother of little Suri Cruise.

Katie Holmes - temporarily unfettered by the shackles of Tom Cruise - has been keeping rather flirtatious company with her co-star in her new movie, Mad Money, according to both Life & Style Weekly and MSNBC.

Some lingering clinches with co-star Adam Rothenberg (below) during filming have gotten tongues wagging, even though Katie is not supposed to have a love interest in the flick. 

Sounds downright Angelina Jolie and Olivier Martinez-like to us.

Holmes has made herself at home in Shreveport, La. to film the movie, which also stars Diane Keaton and Queen Latifah. Sounds like a real winner. Tom Cruise has reportedly tried to spend as much time as possible near his bride.

When one is a helpless prisoner, it's easy to see why one would reach out for the warm embrace of another. But still, the pull of Scientology remains strong.

Who will win the battle for Katie Holmes' soul?!
