I'm late to the party. I just discovered that Blake Lively's older half-sister played the titular character in one of my favorite movies from adolescence, 'Teen Witch.' My mind is blown.

Today I was scrolling through Blake Lively's instagram, she's a new follow for me. I found out she dyed her hair 'bronde,' and I wanted to see how it looked.

Fabulous of course, One photo led to me scrolling through her feed and stumbling onto this gem.

At first, I was confused. I thought, 'Whoa, is 'Teen Witch' Blake Liveley's mom?!?' Google said no. I quickly discovered that Robyn Lively is actually her half-sister, and she's on instagram, too! Her feed is filled with great #throwbackthursday photos of her from the film. So of course I had to share from of the best clips below.
