Is Smallville's Tom Welling Engaged to Girlfriend Jessica Rose Lee?

It appears Tom Welling is off the market!

The Smallville actor set off a flurry of speculation that he’s engaged to his girlfriend Jessica Rose Lee after he used the #fiancé hashtag on Instagram on Monday. (A rep for Welling has not yet responded to PEOPLE’s request for comment.)

“Love: from halfway around the world @jessiroselee,” he captioned a picture of himself in Australia FaceTiming Lee, who is in Barcelona.

“#hereslookimgatyou #letsgo #babe#barcelona #goldcoast #aka #sea#beautiful #fashion #happy#smile#fiance #saddleclub,” he added.

Lee, an avid equestrian, has previously referred to Welling, 40, as her fiancé as well.

“To my perfect fiancé — I love you to infinity and beyond,” she captioned a photo of the two in February. “Thank you for all of your unwavering support and super-human love. I am so blessed to have you in my life @tomwelling.”

Though it’s unclear how long they’ve been together, Lee has been posting photos of the couple since as early as 2015.
