I don’t post about Katie’s own private life unless it’s a big news and this counts to that but it will be the only news we both about the two unless bigger things happen.

People – The couple — who met on set of their upcoming Hallmark movie ‘A Royal Christmas Crush’ — recently traveled to Europe together

It’s a real-life fairytale for Katie Cassidy and Stephen Huszar. After meeting on the set of their upcoming Hallmark movie, A Royal Christmas Crush, the Arrow actress, 36, and Huszar, 39, are now dating, a source confirms exclusively to PEOPLE.

“They’re very much in love and just got back from a European trip in which they joined her family in Portugal, then headed to Spain and France, before hitting Monaco for the Grand Prix,” says the source.

Cassidy — who previously starred in the 2011 film Monte Carlo alongside Selena Gomez and Leighton Meester — “very much enjoyed being back in Monaco,” adds the source. While there, the couple also attended a Boem luxury yacht event hosted by Italian music artists Fedez and Lazza. Earlier this month, the actress teased their romance with a cute snap of her and Huszar captioned “#PrinceCharming.”
