Sarah Michelle Gellar was a proud mom as she paid tribute to her husband Freddie Prinze Jr.’s teenage daughter Charlotte on her birthday.

The 46-year-old former Buffy the Vampire Slayer actress – who recently reunited with co-star Seth Green – appeared on Instagram on Tuesday to shout out her firstborn when she was 14.

Leveraging the app’s Stories feature, she shared a short video showing herself in pajama pants with her children’s faces printed on them.

β€œIf you want to embarrass your daughter on her birthday, carry her to her bus stop on her birthday,” she teased.

The star uploaded a silent clip panning the camera over her outfit, which, in addition to the pants, included a black crew-neck sweatshirt.

In addition to Charlotte, Gellar and Prinze Jr. β€” who married in 2002 β€” also share son Rocky, 10.

Sarah also paid tribute to her daughter in a post shared with her 4.4 million followers.

The movie star, who rose to fame in the late 90s, posted two throwback photos.

In one photo, she threw her head back in laughter as a little Charlotte, sitting on her lap, adorably buried her nose in a cupcake.

The second snap featured baby Charlotte wearing coral-colored star-shaped sunglasses and a white eyelet top.

Gellar exclaimed in the caption, “They say girls give you an equal number of wrinkles from smiling and worrying.” Charlotte, since the day you were born, I smile bigger, I laugh louder and I love so much more.’

The heartfelt note continued: β€œAnd as for worry, you are part of me.” One of the best parts of me.

“I love every inch of you (even the teenage part). I must be the luckiest person in the world, because you call me mom. Happy birthday Charlotte. #happybirthday #14.”

The mother of two also showed her fans how the family of four celebrated the special day.

She shared a photo of the inside of her fridge, which featured two boxed cakes sitting on one of the shelves.

“Two birthdays, two cakes, one @sweetladyjanecakeshop and one @ashleylebo,” she wrote, tagging a friend with a private Instagram profile.

Then, the longtime entertainer shared a photo of one of the cakes, which paid tribute to her as a mother.

“There’s even a cake for me, after all I did the hard work,” she wrote above the baked good.

The delicious dessert had white icing and was decorated with a strawberry, raspberries and blueberries.

She advised her followers: “And if you’ve never tried @sweetladyjanecakeshop, #tripleberry cake will change your life.”

Sarah is adamant about protecting her children’s identities while they grow up, due to her and her husband’s fame.

The two actors got engaged in 2001 after meeting on the set of the 1997 horror film I Know What You Did Last Summer. The ’90s Hollywood hot couple went on to star as Fred and Daphne in the two live-action Scooby-Doo films in 2002 and 2004.

Earlier this year, Gellar revealed to The Hollywood Reporter that his daughter wants to follow in his footsteps as a performer. β€œDoes this scare me? Well, we have rules in place,” she said.

“She can’t be in front of a camera until she graduates from high school,” Sarah told the outlet. She added: “She said to me: ‘It’s unfair. You were a child actor.” Yes. But I wasn’t the child of two famous parents.
