Antonio Banderas' daughter is finally grown up and she looks gorgeous in a bikini

The actor's daughter is all grown up today, taking a leaf out of her parents' book when it comes to her budding career, and a beautiful replica of her famous mother.

Stella Banderas, the daughter of actors Melanie Griffith and Antonio Banderas, came of age in September 2017 when she celebrated her 21st birthday.

She may have fallen under her half-sister Dakota Johnson's shadow after the actress was cast in the seductive "Fifty Shades of Grey" films, but Stella has also started an acting career of her own.

She has recently caught the public's attention when she appeared on the Gucci Cruise 2018 fashion show at Palazzo Pitti in Florence, Italy.

The blonde beauty accompanied her half-sister on that occasion.

She showed up at the Gucci event in a cream-and-black mini-dress. She paired her attire with six-inch platform wedges with red-and-black straps.

On the same day, Stella posted a photo of herself in a blue bikini to her Instagram page.

The baby blue triangle-cut bikini was accented with white lining. She was lying on a lounger outside on top of a towel, soaking in the sun's rays with her hair tied back off her face and neck.

Stella was born in 1996, the same year Griffith and Antonio married.

In 1999, Stella appeared in "Crazy Alabama" with her mother. She also appearaned in an episode of "Celebrity Page" in 2015.

Her parents met and fell in love on the set of the comedy "Two Much." They divorced in 2015, but have maintained an amicable relationship for the sake of their daughter.

Griffith and Antonio, who announced that they were separating in June 2014, have always celebrated their child's milestones together.
