Melanie Griffith and Ex Antonio Banderas All Smiles for Daughter's Graduation

Though they split last summer, Melanie Griffith and Antonio Banderas got together over the weekend for their daughter, as Stella Banderas graduated from high school.

Griffith, 57, posted a pic hugging her daughter on her special occasion. A tattoo on her arm which she had gotten in honor of Banderas — before he became an ex — is covered with a bandage.

Next, she posted a pic with Stella and Antonio.

"Father and daughter celebrating at Baccalaureate luncheon! So sweet!!" she wrote.

Then, there's a pic of all three.

"Mama, Stella and Papi Our angel is amazing. Beginning the next chapter of her life! Freedom!!" she wrote.

Another of the family.

"Me and my fabulous kids! Stella, Alexander, and Dakota my joy, my heart, my life is theirs."
