Officially young(er) and in love: After months of romance rumors, Hilary Duff has finally confirmed a relationship with her personal trainer — a healthier heart, indeed.

Duff, who finalized her divorce from former NHL star Mike Comrie in February, posted an Instagram photo last night (October 16) in which she and Jason Walsh are lip-locked in black and white. "Date night with J," she captioned the shot to equal parts confusion and approval from followers. "You upgraded, girl," one wrote, while another added "SINCE WHEN."

Duff and Walsh have sparked gossip about their relationship over the past few months after appearing at events together, according to Us WeeklyAnd Duff nearly let the cat out of the bag in September during an interview on Good Day New York.

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

Duff and ex-husband Comrie married in 2010 before separating in 2014 and officially divorcing in 2016. They have a four-year-old son named Luca together.

"I don’t want to sound bitter because I’m definitely not, but I don’t know if people are meant to be together forever," Duff told Cosmopolitan in March 2015 in light of the split.
