In the Hot Properties column Sunday, Ruth Ryon reported that Cruise, 44, just paid nearly $35 million for a home in Beverly Hills, which casts some suspicion on rumors that Homes and her older Scientologist husband have hit a rough patch.
Celebrity tabloid Life & Style reported that Holmes, 28, was spotted "flirting" with her "Mad Money" co-star Adam Rothenberg. Jada Pinkett Smith defended the marriage to People magazine.
Life & Style also reported last month that Holmes was unhappy with Cruise's controlling ways and wasn't adapting well to Scientology.
"I think everybody has this image: Poor little Kate, she doesn't have the strength to take care of herself. People don't know that behind all that grace is a tiger," Smith told People. "I've witnessed it! I've had conversations with Kate personally where the tigress comes out of her, that fight."
Ever since Cruise jumped on Oprah's couch in 2005, the country has been mystified about the romance between Holmes and Cruise. Holmes gave birth to a daughter, Suri, a little more than a year ago. They married in Rome last November.
