Mick Jagger, 78, and Melanie Hamrick, 34, looked like a loving couple on a hotel balcony in Miami, FL last week. The Rolling Stones rocker and his girlfriend were dressed in comfortable-looking casual attire, including a long-sleeved shirt for him and a tank top for her, in pics as they happily chatted and got cozy with each other during the relaxing day. They flashed smiles as they enjoyed the seaside vista below and appeared relaxed.
