Katie Holmes is celebrating her boyfriend Jason Bard Yarmosky's birthday!

Taking to her Instagram handle on Tuesday, the 47-year-old actress shared her adoration for Jason, wishing him "a very happy birthday."

“Happy Birthday to the best of the best…,” she penned in the caption while tagging the New York City-based artist.

For those unversed, Katie and Jason sparked romance rumors on July 10 when the two were spotted holding hands at a screening of The Invite in East Hampton.

“He was whispering in her ear, and she was laughing, they seemed very easy together and there was a smile on her face all night,” the insider told People magazine at the time.

“They sat together during the movie, she had her head on his shoulder at one point. They looked very cute," the source continued.

Later, the source close to Katie revealed that the Dawson’s Creek alum and the artist hit it off while at a dinner.

“They went on a date shortly after and she finds him interesting,” the confidant said. “Katie has always been drawn to people who are creative."

"She loves being around people who are passionate about what they do. She enjoys learning and experiencing new things," a tipster added.
