Hilary Duff has finally confirmed long-circulating rumors that she’s dating her personal trainer, Jason Walsh.

“We have [found a little ‘like’ with each other],” she told host Rosanna Scotto.“We’ve known each other for a really long time and he’s a great guy and we have a lot of fun together. It’s nice to have that excitement in my life.”

Asked if the pair are in a relationship, the Younger star laughed and threw her hands up, indicating, ‘Yes.’

The two have been linked romantically for months and speculation deepened after they were photographed together in New York City on Saturday, holdings hands while shopping in Soho, then enjoying a dinner date in Tribeca. Duff, who has a 4-year-old son named Luca with Comrie, was also seen getting pizza with Walsh on Sunday evening.

“They are officially dating,” a source close to Duff tells ET. “They started as friends and are now full-on dating. They are having fun and Hilary really likes him. They are getting pretty serious. Jason is with Hilary in New York now and will stay with her there until she finishes filming. Everyone is so happy for her. She deserves the best.”

“They’re all still close,” says the insider. “It’s amazing how they have been able to stay on good terms, especially for Luca. Haylie and Mike always had a great relationship, and Mike and Matt are friendly. Mike is a great dad and really loves Luca.”
