Well, we have even more evidence that Taylor Swift is making a huge mistake with her dating life. As we’ve reported before, it’s looking more and more like Swifty dumped Taylor Lautner and began quietly, secretly dating John Mayer, douche extraordinaire. The latest evidence comes out of Nashville, where Mayer and Keith Urban were filming an episode of VH1’s Crossroads, and Taylor came to Nashville to sing a few songs or something. While Mayer and Swift were in Nashville, it seems they went out on another date:

Last night John Mayer was in Nashville for the Crossroads taping with Keith Urban. More on how that went down later.

Taylor Swift attended amid speculation that she and Mayer are now dating. My sources tell me she was backstage before the show, totally crushing on him, very “smitten”, flirting, like a young girl intoxicated by attraction to an older man, too young to separate artistry from douchery.

On Monday night, Taylor and Mayer went out for dinner with a large group. I’m told this is how she gets around her mom. Momma Swift is a wary parent and some say Taylor arranges their time together in crowds so as not to hear it from her mom later on. There are some rumours that John was seen at her place afterwards. This has not been substantiated.

At the performance however her affection for him was undeniable. She was cheering enthusiastically in the audience, making hand hearts at him constantly, and the buzz among industry insiders and crew is that they’re definitely dating. Some have even told me that this is why she called it off with Taylor Lautner. Because while there was no spark with Tom Cruise’s mini me, she was compelled to explore the intensity of her feelings for John.

As you can imagine, for squeaky clean TSwizzle, a hook up with Mayer, currently extolling the virtues of masturbation in the pages of Rolling Stone, is problematic for her image. It remains to be seen then how her team will manage the progression of this relationship.

Kanye was nothing. Nothing compared to how this dicksplash could destroy her. Then again, she’s young. And it happens. We are/were all due for a transformational devastating affair. At 20, for Taylor, it’s only a matter of time. It’s just really too bad it could be him. Because on a romantic resume, John Mayer is a straight up smear.

Good Lord, I hope Swifty’s mom nips this in the bud. But that might not work – I know that at that age – well, younger actually, hearing that mom didn’t approve of a dude made him more exotic. What needs to happen is for Swifty’s friends, her business team, and the public at large to tell Swifty unequivocally that a dalliance with Mayer would ruin her reputation, and she would never be able to wash the stench of smug douche off.

Don’t believe me about Mayer? Lainey went on to describe the scene at the Crossroads taping:

The musicians had plenty of opportunity to prep. Of course they did. As the two headliners, they’re pampered and coddled, and nothing happens until they are ready. So as they take their places, a production member took to the stage to explain to the audience how the show was being filmed. This was told to me and I’m passing it to you to illustrate that Mayer had more than enough time to get set.

Once the audience had been briefed, they were ready to begin. And Keith began. And as soon as he began, John Mayer had to stop him. To the effect of: “I don’t want to be that guy who has to change his guitar strap but I’m using the blue one and I have to have the green one”. Or green to blue. And so it continued. A seemingly endless stream of consciousness as though the people sitting there actually cared about all the profundity spewing from his mouth. This however did not seem to faze Taylor Swift. Oh honey…

As such, I’m hearing that John and Keith did not exactly spark the kind of chemistry that everyone was hoping for. Because, ultimately, it’s always the John Mayer Show. My sources tell me Keith was not comfortable. And this of course makes a tour rather tricky.

Oh, yes. My guess is that Mayer still fancies himself a comedian, and he still thinks that whatever farts out of his mouth is so profound, so inherently hysterical, so “deep” that us mere peasants cannot even fathom the hilarity and profundity. Nevermind that he’s racist. Nevermind that when an interview doesn’t go his way, he threatens sodomy. Nevermind that Mayer might also have his eye on Kate Hudson. Actually, that last one might work. Swifty won’t like it if Mayer has his eye on another blonde. Somebody tell her!
