According to People magazine, the two recently took a trip to Miami.
Yesterday, the two singers worked out together in the excercise room of their hotel. In the evening they went hand in hand to dinner at Shore Club Nobu.
The stars have insisted that they were only friends before they fell in love. At the dinner table, Mayer reached across the table to hold both of Simpson’s hands. A witness said, "They were talking and laughing the whole time. She was constantly fixing herself to make sure she looked her best for him."
Simpson, 26, and Mayer, 29, enjoyed the Florida sun for several days. Mayer will perform in concert in Jacksonville, Florida on Thursday.
