Aniston and Mayer 'really into each other'?

Washington, May 13 : It seems that the romance between Jennifer Aniston and John Mayer is hotting-up.

According to sources, the pair was spotted having a hot time in Miami this weekend.

This is the second time within a month the two of them have been seen together, as they hit the pool of the Mandarin Oriental Hotel on Saturday May 10, where they had spent five days together in April.

According to an eyewitness, the two ordered drinks and then rubbed sunscreen on each other before jumping in the pool.

"It seems like they're both really into each other!" the eyewitness told Usmagazine.com.

The "very happy and relaxed" couple alternated between gazing into the ocean, playfully teasing each other in the water and talking intently.

They were later seen in the night at the Marley and Me wrap party at Nikki Beach Coconut Grove, where Mayer served as Aniston's date.

The pair really seemed to be enjoying each other's company as they cuddled and laughed with other guests, even being one of the last to leave at 1:50 a.m.

Last month, Mayer had flown to Miami to spend time with the 39-year-old actress, and during their time together, he had fresh flowers delivered nearly every day to their shared hotel room

"She just always seemed like a lot of fun to him," a Mayer insider said.
