Sarah Michelle Gellar had plenty to celebrate this past week.
In case you missed it, the Buffy the Vampire Slayer alum, 47, marked her son Rocky's 12th birthday by sharing a sweet tribute to the tween on Instagram, including a rare childhood pic. And guys, I'm still not over the uncanny resemblance between Rocky and his dad, Freddie Prinze Jr. Gellar captioned the post, "Raise your hand if it’s your birthday!!! 12 years ago, Charlotte told us all she wanted for her third bday was you. And even though you weren’t due for another three weeks, she got her wish…and we all got the greatest gift. You. Happy birthday Rocky!!!!"
