Jennifer Aniston and John Mayer’s on-again-off-again-on-again-off-again-on-again-off-again relationship is on again. Kinda. Sorta. According to Gatecrasher, John and Jen are still sleeping together, but it sounds like they’re barely in a relationship. Why? Because John really feels like he needs to focus on his music right now. You know, that epic, soul-stirring stuff he comes out with. Yeah, he needs to create more of that, and it’s such a priority in his life that he doesn’t really have time for Jen anymore – aside from the sex. Oh, and he also needs to work on his T.V. show. Don’t forget, Mayer thinks he’s very, very funny.

It’s not that John Mayer isn’t that into Jennifer Aniston — he’s just too busy for her. The rocker, who was caught on a business date with a beautiful blond last week at Marix Tex Mex restaurant in Santa Monica, was back with Aniston at a private Super Bowl bash in Calabasas, Calif., on Sunday. And while that may signal another “on” phase for the on-again/off-again couple, pals say Mayer is way too busy for a serious relationship with Aniston, and instead wants to focus on himself.

“John’s goal is to keep a low profile this year, and Jen is about as far off from low-profile as you can get,” a source tells us. “He just wants to keep out of the spotlight and finally concentrate on his music.” Mayer is working on an album tentatively titled “Battle Studies,” a followup to 2006’s “Continuum.” “He’s always in and out of the studio,” a second insider reveals. “That’s his focus.”

In addition to his music, Mayer is in talks to film a sketch-comedy show for CBS. “It’s more of a variety show that will resemble VH1’s ‘John Mayer Has a TV Show,’ ” says the snitch. “That’s where his bear skit was born, so think along those lines. Combine a bunch of funny shorts, and you’ll have the show.”

And what about Aniston, whose flick “He’s Just Not That Into You” opens Friday? Insiders say she’s sick of her inconsistent relationship with Mayer. “He keeps her in limbo,” the snitch reports. “She and John see each other and sleep with each other, but are they getting ready to walk down the aisle? No. Jennifer knows that. But at the same time, no girl wants to spend every night alone. She needs to accept the title of her new movie to be the title of her life.”

There are few men that are as good at “focusing on themselves” as John Mayer. Really, he’s made a career out of looking out for himself and taking care of his needs. I’m really glad to hear he’s getting back to that, because he has just been too distracted taking care of others. What bullshit. The only thing funnier than that is the line about how his goal for this year is to “keep a low profile.” John Mayer is the biggest attention whore since Paris Hilton. In fact, that’s exactly who he should date: they’d be perfectly matched.

Gatecrasher says Jen’s got other options, so she shouldn’t be hanging all her hopes on Mayer. Which I doubt she’d do no matter what.

If things don’t work out with Mayer, Aniston has a second singing suitor waiting in the wings: “Rock of Love” bad boy Bret Michaels.

“Bret is really crushing on Jen,” a pal of Michaels confides. “He says she’s the kind of girl you can have a good time with, but can still take home to Mom.”

While we think Michaels could rock Jen’s love, a Mayer pal says: “Jen can date whoever she pleases, but she should keep in mind that John’s tour bus is so much better than Bret’s!”

Ick. I really, really hope Jen wouldn’t consider dating Bret Michaels. Really, he’s the only guy I’d less like to see her with than John Myer. She deserves someone nice who will treat her well and make her a priority. Not some douche who’s going to cast her aside whenever he wants to make some more of his crap-ass music. And more importantly, not someone who looks like Bret Michaels. His face is more offensive than anything else in this article.
