She added: ‘Stunning. Happy birthday, Mia.’

In the accompanying picture, Mia donned a black-and-white polka dot shirt and grey slacks as she sat in a garden, with a lemon tree behind her.

Her hair was styled in waves, and she appeared to be makeup free for the occasion.

In another post shared by her father, Mia showed off her edgy side by striking a pose in the backyard of the family’s home.
