Mia is 17 years old and has an older brother named Jacob Lawson-Black. Their father and mother died when they were younger, so Mia relied on her brother to take care of her until she was old enough to fend for herself.
Mia loves to hang out with her cousin Carlos Pena Jr. and his friends Kendall Schmidt, James Maslow, and Logan Henderson when they have time off from their TV show, and when they are not on tour. Mia hopes to become an actress or a professional dancer like her cousin. Mia is a Vampire and is currently TALKING TO SOMONE.
