Antonio Banderas and Melanie Griffith Take Daughter Stella to Charity Gala

The family that walks the red carpet together, stays together.

Just weeks after Antonio Banderas, 51, and Melanie Griffith, 54, squashed rumors of marriage trouble, the pair looked happier than ever when they stepped out with daughter Stella at a charity event in Marbella, Spain.

And all eyes weren’t on the famous couple, who first met in 1995 on the set of Two Much. Stella stunned in a curve-hugging, floor-length black dress at the Starlite gala. With her wavy locks pulled back into a simple chignon, the 16-year-old looked like a natural as she posed for photographers.

In 2010, Banderas spoke fondly about his relationship with Stella. “I have one date night with my daughter every week. I take her for dinner by herself … and we can talk, spend some time together,” he told PEOPLE. “We just try to be dynamic in our relationship to the family and it’s fun too.”

The proud parents, who married in 1996, were smiling, whispering to each other and laughing with Stella, taking time to pose with family friend Daryl Hannah, who also attended the event.

“They really are very happy together,” a source close to the couple told PEOPLE in July.
