Melissa Joan Hart wishes she had ''taken a chance'' on Ryan Reynolds.

She claims the pair had crushes on each other when they worked on the movie version of 'Sabrina The Teenage Witch' together when they were both 19 but their mutual attraction did not go anywhere because she had a boyfriend.

Melissa, 40, told Australia's Studio 10 talk show: ''We were smitten and cute. He was adorable. He was a really nice guy.

''He wasn't like, the Ryan Reynolds everybody knows these days. You can see in the clip the crazy hair. He was sweet - he was very sweet.

''I had a boyfriend at the time. [He] 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!''

Speaking previously about their attraction, Melissa admitted they shared a kiss but she ultimately chose her then-boyfriend over the 'Deadpool' hunk, who is now married to Blake Lively.

She said: ''I chased him down, got in front of his car and just kissed him and then made out with him all night. Then I had to call my boyfriend the next day and explain it.

''He came to New York to visit me. But I think he wanted something more but I decided I was going to stick with my boyfriend.''

Melissa has been married to musician Mark Wilkerson since 2003, and the pair have three sons together - Tucker, four, Braydon, nine, and Mason, 11.
