Sarah Michelle Gellar gave fans a rare glimpse at her daughter Charlotte Grace Prinze as she celebrated the teen's 15th birthday on Thursday.

The Buffy star, 47, shares Charlotte and 11-year-old son Rocky James Prinze with longtime husband Freddie Prinze Jr., 48.

She and Freddie wed back in 2002 after starring together in a number of hit films — including I Know What You Did Last Summer and live-action Scooby Doo — in the late 1990s and early 2000s.

In honor of their eldest's special day, Sarah shared a heartfelt tribute to Charlotte on Instagram.

She included footage of the teen showing off her impressive tumbling skills on a training mat in the backyard of their Los Angeles home.

Charlotte, wearing white shorts and a yellow tank top, is seen proudly performing a cartwheel back-handspring for her mom.

Sarah set the video to the tune of Stevie Wonder's 1980 hit Happy Birthday.

In the post's caption, the Cruel Intentions star expressed her 'love' for her teen daughter.

'We are all jumping and flipping Charlotte because it's your 15 Birthday!! I don't know how it's possible but every year I love you more,' she wrote, along with a string of birthday-themed emojis.

Just one day after Charlotte's birthday, Sarah and Freddie's son Rocky will turn 12-years-old.

The beloved Hollywood couple waited six years after their 2002 nuptials to become first-time parents.

Sarah was 32-years-old and Freddie was 33-year-old when they welcomed Charlotte on September 19, 2009.

They added Rocky to the family three years later on September 20, 2012.

In a previous interview with PEOPLE , Freddie said that he and Sarah were 'so happy' that they waited until their 30s to start a family.

'I'm so happy we didn't have kids in our 20s — I just didn't know a thing. You have so much more patience in your 30s, and I feel like I appreciate this so much more,' he told the outlet.

Freddie and Sarah are fiercely private when it comes to their children, who they've only shared on social media a handful of times.

When they do share photos, the protective parents typically cover their kids' faces with emojis to protect their privacy.

Back in late August, Sarah announced on Instagram that Charlotte had officially started her freshman year of high school.

'Time is a b**ch,' the former CW star quipped.

She included a video of herself dancing with both her daughter and son's 'First Day Of School' signs in the foyer of their home.

Charlotte made her red carpet debut in 2022 at the premiere of Sarah's Netflix thriller Do Revenge.

The mother-daughter duo were photographed hanging out with Sarah's co-stars Camila Mendes and Maya Hawke at the LA-based event.

Last year, Sarah revealed that Charlotte has caught the acting bug after years of watching her parents onscreen.

'Does it scare the s**t out of me? Well, we have rules in place,' she told THR . 'She can't be in front of a camera until she graduates high school.'

She said that Charlotte thinks the rule is 'unfair' because Gellar started acting at age four.

'"Yes, I was [a child actor]. But I was not the child of two famous parents,"' Sarah recalled telling the teen.

'I'll never stop her from being on a set. But she's just not going on camera while she's living under our roof.

'There'll be different expectations for her, so she needs to learn everything there is first,' the starlet explained.

Earlier this month, Sarah and longtime husband Freddie celebrated their 22nd wedding anniversary.

To mark the milestone, the blonde beauty uploaded a sweet selfie with the She's All That hunk to Instagram on September 1.

It showed Freddie hugging Sarah from behind as they vacationed at an oceanside resort.

She simply captioned the post: '22
