The on-again off-again couple were spotted getting cozy in WeHo on Tuesday, sources report.

They arrived around 10 p.m. and sat indoors with three pals.

Aniston — who ordered her usual grilled chicken salad — shared a bottle of wine with the table.

Says the witness of the couple: “They looked like they had the best time. They were holding hands at one point and seemed very much back on.

“She seemed extremely happy to be back with him,” the insider tells Us. “They were close and laughing the whole time with their friends.”

I don’t know what sounds more unbearable, living on a constant diet of grilled chicken sandwiches or dating John Mayer. I’m truly stumped.

That’s what the National Enquirer wants you to think.

They just flew into Los Angeles together, landing at 4:05 Pacific Time on Monday, October, 13, The ENQUIRER has confirmed.

The pair split in August after a 3 ½-month romance, but they met up in Manhattan recently and looked like lovers when they came back to California together.

“They were very lovey-dovey,” said an insider. “They kissed several times and hugged each other tightly.

“John gave her a long, lingering kiss.”

A long, lingering kiss?

He was just probably trying to suck the pot smoke out of her lungs. There’s enough in there to get a decent buzz, I’ve heard.

After all the rumors about how he’d cheated on Jennifer Aniston left and right, I guess John Mayer wanted to set the record straight. He chatted with reporters after a workout this weekend, saying that “there’s no lying, there’s no cheating, there’s no nothing … Jennifer Aniston is the smartest, most sophisticated person I think I have ever met.”

He went on to say that “People are different, people have different chemistry. I ended a relationship to be alone, because I don’t want to waste somebody’s time if something’s not right.”

Eh, we all know that’s bullshit. He and Jen broke up because Jessica Simpson sent one too many death threats.

So far, no comment from Jen’s camp.

Dude, so how long did it take for this “serious relationship” to fall to pieces? A month? Two?

Sources are reporting that John dumped Jen.

“There’s been a bit of tension for some time,” says a source close to 30-year-old John. “They initially opted for a break, hoping a trial split might make them stronger. Sadly it doesn’t seem to have worked. John took the decision to end things as he felt he just wasn’t ready for the level of commitment that Jennifer deserved.”

Word is that Jen’s already got a new man — some sort of male model. Sigh. Isn’t she bored of the male models yet?

This is a fun little item from Page Six:

JOHN Mayer might have broken Minka Kelly’s heart when he left her for Jennifer Aniston – but he had the decency to call her before the news about them hit the press. A Kelly pal said, “Minka [above] received a call from John prior to the story breaking about his relationship with Jennifer. He apologized to Minka, ‘Sorry, but I’m really in love.’ ” She found that interesting as, “during his relationship with her, John mentioned, ‘I don’t really get this Jennifer Aniston thing.’ ” Mayer’s rep declined to comment.

Well, I’ll tell ya, John Mayer’s getting plenty of Jennifer Aniston’s thing these days.

He’s gonna get bored of her so quick.

On the heels of initial reports that the two were spotted sharing a meal in Miami, we’re now hearing that they later had an intimate dinner that lasted until 1 a.m.

They had a “cozy” dinner at Casa Tua in Miami Beach, and were spotted holding hands as they returned to their hotel.

Damn.

What do we think of this new pairing, kids?

Yup.

I wanna pet that.
