Katie Holmes is a mistress of disguise!

A source tells Us Weekly that for a recent L.A. rendezvous with boyfriend of two years, Jamie Foxx, the Ray Donovan actress, 36, “put on a wig and hat to meet him at a hotel.”

The relationship is a multi-city operation: While Holmes, who has been filming All We Had in NYC, supported the Grammy winner, 47, following his Aug. 22 SLS Las Vegas gig, “Katie sent Suri from NYC to L.A. with a nanny,” says a Holmes insider.

The soon-to-be fourth grader, 9, the source adds, needed to be back in time for school. Suri also took a Sept. 7 trip to Disneyland while Mom visited Foxx’s Thousand Oaks, Calif. mansion.

“Katie is so in love,” adds the insider. “I don’t know if he’s dating other women, but she isn’t dating other men. She is all about Jamie.”

Us Weekly broke the news of their tryst in October 2013, and obtained an exclusive first photo of the two holding hands this March. Though they keep their romance under wraps in public, their friends and family are well aware of their shared sentiments.

In May, Holmes dropped the L-word following a phone call with Foxx.

"She said she loved him," another source told Us at the time. "She always gushes about how amazing he is and the joy he brings into the world.”

And Foxx is “quick to call [Holmes] 'my girl' to pals,” a separate source previously noted. "As in, 'My girl is calling.’”
