Jennifer Aniston and musician boyfriend John Mayer share a sweet kiss at her Marley & Me wrap party held at Nikki Beach in Coconut Grove last Sunday.

“It was nice that she brought him,” one party goer told Us Weekly after the pair were one of the last to leave the after-party.

Another source reveals, “She’s really into John, and the nine year age difference doesn’t bother her for a second. Jen’s already telling friends she’s falling in love with this guy.”

John Mayer shows off the perks of being a celebrity in his latest blog entry, showing the world the latest and greatest from RIM — The Blackberry Bold. Here’s what he blogged:

“Hi. My name is John. I like cool stuff, early. Is that so wrong? Isn’t it funny how there are no more “geeks” in the world? Remember the distinction? Now everyone is a geek. So the word is dead. Maybe that’s where “douche” was born. The human need to separate and demean. Who knows. At any rate, It has blazing fast 3G and twice the screen resolution, and the fonts look like something out of the New York Times. Which makes “WHERE R U” read as if it were an op/ed.”

Where do you think Mayer took this photo of his new Blackberry? Jennifer Aniston’s hotel room, perhaps??

Jennifer Aniston and John Mayer continue their lovefest in the Big Apple as the new couple are spotted out and about on Thursday.

While clutching onto a bottle of smartwater, Aniston was seen leaving the Ritz Carlton and browsing the Upper East Side’s Naga Antiques Store, which specializes in Japanese screens and fine Asian works of art.

Just last night, Janiston enjoyed a romantic dinner together at The Waverly Inn. Some photos (albeit dark and grainy cell phone ones) from inside the restaurant during their dinner have started to surface.

Aniston can be seen wrapping her arms around Mayer’s neck and kissing his cheek. Mayer is also pictured putting his hand on Aniston’s shoulder while sharing a laugh together.

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.”

John Mayer opened up at yesterday’s MET Costume Institute Gala about the photos of him and Jennifer Aniston in Miami. Here’s what he told multiple media outlets:

Entertainment Tonight: “Listen, this is not a scandal, this is not an issue, this is not a problem, this needs no spin control. This is me living my life and a guy with a really powerful lens and I don’t fault him, I don’t fault anybody, I don’t fault you, I don’t fault this or that. There are much worse problems in the world. Everything’s cool!”

Extra: “I don’t mean to deny it, but sort of deflect it. You have the photograph. You think it’s photo-shopped?”

Associated Press: “[I give the pics a] double thumbs up. “You know what I did? I looked at it and I said, ‘That’s about right.’ What am I going to say, ‘That’s not me’? You carry on and you enjoy yourself and you continue to live with dignity and everyone has fun.”

John Mayer arrives at “Superheroes: Fashion and Fantasy” - Costume Institute Gala at The Metropolitan Museum of Art in New York City on Monday.
