Jennifer Aniston and her reported new beau have been enjoying the summer weather together in Miami.
Pictures show the couple relaxing at the pool of the Mandarin Oriental hotel, with Aniston looking stunning in a skimpy bikini.
After a spot of sunbathing on the loungers, the couple cooled down in the pool.
Mayer, 30, is reported to have flown from New York to be with Aniston in Miami, where she is currently filming Marley and Me with Owen Wilson.
The singer-songwriter is no stranger to having the spotlight on his relationships, having dated other high-profile beauties including Jessica Simpson and Jennifer Love Hewitt.
Despite the nine-year age gap between the couple, friends of Aniston are reportedly hopeful the relationship could be more than a summer fling.
Her former flames include Brad Pitt and Vince Vaughn.
