Katie Holmes and her boyfriend are Instagram official.

The "Dawson's Creek" star's beau, Emilio Vitolo Jr., took to Instagram on Friday to celebrate Holmes' 42nd birthday with a loving tribute.

Contained in the post was a gleeful black-and-white photo of the actress sitting in the lap of Vitolo, both wearing massive grins in what appeared to be a restaurant.

"The most amazing, kindest, beautiful person," wrote the pro chef. "Every time I see your face it makes me smile."

Vitolo, 33, is reportedly the first man Holmes has felt comfortable with being "authentically herself" rather than morphing herself into the person her partner wants.

"They adore each other and can't get enough of one another," a source told Entertainment Tonight in October.

The pair met in the fall of 2019, which is why their relationship has blossomed so quickly, the source said.
