It's Serious! Katie Holmes Introduces Jamie Foxx's Daughter To Suri

Katie Holmes is getting so close to boyfriend Jamie Foxx that she's even taking his daughter out for a ladies lunch with her own daughter, RadarOnline.com has exclusively learned.

The 37-year-old Dawson's Creek actress and the 48-year-old best friend of Tom Cruise have been trying to keep their relationship under wraps, but a source told RadarOnline.com they spotted Holmes out to lunch with his pretty offspring in Beverly Hills.

"Katie and Suri Cruise and Corrine Fox were all at the Honor Bar together having a girls day out," the eyewitness told RadarOnline.com.

"Corinne was so cute with Suri, and the three of them looked like they were having a lot of fun together."

The 21-year-old model is the 2016 Miss Golden Globes, an honor often bestowed on children of celebrities.

"They were all so relaxed with each other, it seemed like they knew each other really well and spent time together before this day," the source said.

Holmes was very close to her step-daughter Isabella Cruise when she was married to Tom, and even employed her at her Holmes&Yang clothing line.

Holmes and Suri live in Los Angeles and their girls date with Corinne was just another example of her blossoming romance with Foxx.
