Cue the waterworks: Jennifer Garner and Blake PrestonBen Affleck's oldest child, Violet Affleck, is graduating high school.

The former couple's 18-year-old daughter has crossed the stage, leaving the "13 Going on 30" star emotional.

"Tell me you have a graduate without telling me you have a graduate. 🎓 (bless our hearts 🥺♥️😭)," Garner, 52, wrote on Instagram Monday.

The actress shared a photo carousel of her crying in what looks like an auditorium, outside and on a plane. Included was a video of Garner on the plane, still crying, saying, "How are we gonna make it? What are we going to do?" The set of photos then included Garner in a pair of 2024 sunglasses.

The relatable emotional moment garnered comments from fellow stars.

"Oh honey … I know," Reese Witherspoon wrote. "You have done a great job , mama! I will be here for support and lots of hugs."

Garner has discussed the difficulty of parenting teens. The actress told People in an interview last year that she has a "huge heart for teenagers" even though the one she parents in her 2023 film "The Last Thing He Told Me" isn't her biggest fan. "I see how hard it is to be a teen right now," she said. "The teenager in the story … she's mean."

The "Daredevil" alum said her children aren't exactly first in line to watch her shows or movies.

"My kids don't love to watch me in things," she told InStyle last year. "I think it's a little weird to watch your mom kiss someone or cry. … They don't want to see me sad and they don't want to see me in a romance. They don't love seeing me play someone else's mom, honestly. I don't know if they'll watch this."

Garner and ex-husband Affleck share three children and were married from 2005 to 2018.
