Katie Holmes is reportedly considering getting back together with Tom Cruise.

The actress-and-designer is allegedly thinking of taking back her ex-husband if he "leaves Scientology".

This follows reports earlier this month that claimed the Hollywood actor was considering ditching the church if it meant possibly reuniting with Katie and his daughter Suri.

"Katie is a sucker for the big romantic gesture," a friend told British magazine Grazia.

"Tom swept her off her feet the first time around, and if he goes ahead and leaves Scientology for her, that would be seriously tough for her to resist."

Katie filed for divorce from Tom in June this year. Since their divorce was finalised, Tom has reportedly been suffering from the lack of contact with his six-year-old daughter.

It is thought Tom's connection with the Church of Scientology was one of the contributing factors to their break-up.

Katie - who was raised a Catholic - reportedly didn't want Suri to be sent to a special Scientology camp or to be taught at one of the religion's schools.

"The religion is the biggest thing in his life. If he left that behind for her, it would be immense," the source continued to Grazia. "But it seems that may be what he's talking about doing. He misses Suri like crazy."
