Hart was in a committed relationship when the pair shared an on-screen romance in 'Sabrina the Teenage Witch.'
Melissa Joan Hart is pondering past love!
The Melissa & Joey star reminisced about1996's Sabrina the Teenage Witch TV movie, where she shared an on-screen romance with Ryan Reynolds, that, as the 40-year-old actress tells it, had the potential of becoming something real.
"He was very sweet. I had a boyfriend at the time but we were smitten and cute and he was adorable," Hart shared during an appearance on Australia's Studio 10. "He was a really, really nice guy, probably would have been a great boyfriend, and I didn't end up with the other guy, so maybe I should have taken a chance!"
Of course, Hart has been married to Mark Wilkerson since 2003, while Reynolds tied the knot with his wife, Blake Lively, in 2012. But just because they're in happy relationships doesn't mean she can't wonder about what might have been once in a while!
The Sabrina actress previously detailed her almost fling with the Deadpool star in her 2013 memoir, Melissa Explains It All: Tales from My Abnormally Normal Life.
"Though I was madly in love with James, my boyfriend of six months by then, Ryan and I spent plenty of time together," she wrote, calling him "cute and charming," though, sort of an "oddball."
"Even so," she continued, "he sure knew how to make a girl feel special."
