(Cover) - EN Showbiz - Katie Holmes has been relying on her "solid friend" Chris Klein for support lately.

The actress filed for divorce from Tom Cruise at the end of last month and they settled the terms of their split in under two weeks.

Katie and Chris were engaged before she got together with Tom and she has reportedly turned to him for help in the wake of the separation.

"Chris has been a huge source of support. They've stayed on good terms since they broke up and he's one of Katie's few really solid friends," an insider told Heat magazine.

Katie and Chris stayed in touch after their break-up and she personally told him when she started dating Tom.

Although they haven't seen each other much over the years, she is said to feel indebted to him following his recent help.

"Because of Tom she was really isolated. She only hung out with people who Tom and the [Scientology] Church had pre-approved, so she hardly has any friends. Having Chris as a shoulder to cry on has been a huge help for Katie. It wouldn't surprise anyone if they became more than just friends," the insider added. (C) Cover Media
