The 33-year-old actress has been looking in to ways to make money since the split, with paid for appearances just one option, reported The New York Daily News.
"People are putting the word out she is willing to do paid appearances and just seeing what opportunities come to her. Katie never did this before her split with Tom. Brands want her to wear their clothing for money, and then she will get photographed in it," a source said.
Holmes will receive USD 400,000 per year in child support from Cruise until their six-year-old daughter Suri turns 18 and the actor has also set up a sizable trust fund for the youngster which Holmes won't be able to access.
"Katie wanted the trust fund put in place for Suri so that their daughter will be able to tap into after she turns 18 years old. Katie has absolutely no access to the money and didn't want to.
"She just wanted to ensure that Suri would have financial security as she becomes an adult. It's a sizable trust fund, but Suri won't be able to fully legally claim it until she is in her 30s," the source added.
