Calling all fans of Sabrina the Teenage Witch!

The popular show first aired in 1996 — and the series' star Melissa Joan Hart has changed so much since the premiere! The actress turns 41 years old today, so we're taking a look back at the cast of the sitcom then and now in honor of her birthday.

Today, 14 years after Sabrina went off the air, Melissa is married to Mark Wilkerson and the two are parents to three sons: Mason, 11, Braydon, 9, and Tucker, 4.

When Closer Weekly asked her which TV character of hers was her favorite, she replied, "Asking me which character was my favorite is like asking which child I love best." Too funny!

"On each show, I was well aware of the positives and negatives of both the character and the experience on set. Clarissa [from Clarissa Explains It All] was a learning environment for me and she was as much of a role model to me as she was to the fans I meet everyday," Melissa continued in the exclusive interview. "While with Sabrina, I didn't quite relate to the character but I was aware of her appeal to the audience. Meanwhile on set (and off) the crew and I were having an absolute blast and it was all during the boom of network television."
