It’s official!

Hilary Duff took to Instagram Sunday to share an adorable picture of herself with Jason Walsh — marking the first time the actress has confirmed she’s dating the personal trainer on social media.

“Date night with J,” she captioned the sweet black-and-white shot of the two kissing.

Romance rumors first started buzzing around the Younger star, 29, and Walsh in summer 2015 when they partied together after the grand opening event for his Rise Nation Fitness Studio in West Hollywood.

In March of this year, the two were spotted on a dinner date in Los Angeles. At the time, a source told PEOPLE the budding relationship was “fairly recent” and “casual.”

Most recently, Duff fielded questions about the relationship during an interview with Fox’s Good Day New York co-anchor Rosanna Scotto last month.

“We’ve known each other for a really long time and he’s a great guy and we have a lot of fun together,” said Duff. “It’s nice to have that excitement in my life.”
