Jenniter Aniston is Strumming John Mayer’s Guitar

John Mayer arrived at the Mandarin Oriental hotel in Miami Beach at 12:30 p.m. today, reports Life & Style.

That’s the same hotel Jennifer Aniston is staying at!

“John came in with another man who looked like a personal trainer,” an eyewitness spills. John was in long gray shorts and a green T-shirt, and he was holding a water bottle. He looked like he had just finished a workout. His hair was still in its new signature cut, and he was in a great mood.”

In Touch is also reporting that after filming for three months in Miami, Aniston has big plans for the wrap party of Marley & Me. The celebration will reportedly take place at Nikki Beach in Coconut Grove on May 10, where John Mayer will perform a special three-song set.

“Everything was changed last minute so John could do this for her. He’s crazy about Jen.” another insider says. “It’s hot and heavy but in that very cool way. John isn’t gong to hide his adoration and he’s telling everyone what a cool chick Jen is.”
