Rumors of Katie Holmes rekindling a relationship with Chris Klein are not stopping any time soon but evidence is hard to find, especially with a source revealing that the actors are trying their very hardest to keep everything about their relationship as private as ever.

A source reportedly told Grazia magazine, "you can't expect Katie to live the life of a single girl forever. She and Chris have been incredibly careful not to be seen together. When he visits, he goes into the building through the underground car park to make sure that nobody spots him." 

The reason for being so secretive is to not embarass Holmes' ex-husband Tom Cruise, and according to the source, Holmes is "very sensitive" about that. 

Holmes and Klein were together way before she met the "Mission Impossible" actor and fell head over heels for him, eventually marrying him and having daughter Suri. The couple divorced in August after six years of marriage. Holmes has since relocated from California to New York, where she now lives with Suri. 

Though his relationship with Holmes did not work out the first time, additional sources told Grazia that Klein has changed and is a better man now than he was before. 

"Chris was a real ladies' man when they were first together...he also had a major problem with alcohol," a source said. "[But] he's really cleaned himself up since then...Katie likes the new Chris a whole lot more." 

Interestingly enough, different sources told Radar Online earlier this week that Holmes was apparently going to stay far away from actors in her new dating life.

The sources told the gossip site, "Katie doesn't want to tie herself down just yet, but she says she's done going out with actors," a source explained to Radar Online. "Her previous relationships with Joshua [Jackson], Chris [Klein] and Tom [Cruise] didn't work out, so she thinks she should look away from her own profession."
