Katie Holmes and Jamie Foxx are showing no signs of slowing down their romance. Lately, it seems as if the two, who once went to extremes to hide their companionship, are easing into the idea of going public with their relationship.

Although the couple doesn’t seem to be planning on making a red carpet appearance together anytime soon, Holmes didn’t have a problem flirting with Foxx in front of a crowd of people during his birthday party.

On Wednesday night, the actor celebrated his 50th birthday with a huge party. While the bash was attended by major stars including Snoop Dogg, Ice Cube, Ludacris and Too Short, Foxx only seemed to have eyes for Holmes

According to TMZ, the actress walked on stage during the bash to talk to Foxx. Holmes was all smiles throughout the conversation as Foxx whispered in her ear and pulled her in close during their intimate conversation.

Although Holmes and Foxx typically keep their distance when it comes to appearing in public, sources told People that the two arrived at the actor’s party together.

Foxx kicked off the night with a quaint celebration alongside his daughters, Corinne Foxx and Annalise Bishop, at a different venue where the actress was not in attendance.

It wasn’t until later on in the night when he met up with Holmes. “They walked in together,” an insider revealed.

“They mostly mingled with other guests and spent very little alone time. It was obvious that Jamie had a great birthday. Katie looked like she had fun as well. She looked gorgeous,” the source added.

This is not the first time that Foxx and Holmes have attended the same event. In early December, Holmes made an appearance at the store opening of Privé Revaux in New York City. Foxx, who arrived separately, is one of the many celebrities involved in promoting the affordable eyewear brand.

In September, the two were spotted holding hands on a beach in Malibu, California, however, a friend close to Foxx insisted that the relationship isn’t as serious as it may seem.

“They’ve been friends for years,” the source told People at the time.

“That blossomed into a wonderful relationship that they both enjoy,” the insider added.

Holmes and Foxx have been romantically linked to one another since 2013.
