John Mayer: I'm Having a Blast with Jessica Simpson

We're sure that her body is a wonderland. Now, according to the boyfriend of Jessica Simpson, a relationship with the beauty is like a trip to Disneyland. It's a lot of fun.

After being pressed numerous times about his fling with the new brunette, John Mayer is done holding back his feelings.

When asked by Time Out New York, "So, what about Jessica? According to Extra, you can't deny you're a couple anymore," Mayer shot back: "I don't think I've ever denied it. When did I deny it?"

Adds Mayer, whose fans might think the crooner and the pop star are an odd match: "I'm having the best time of my life, so if the names don't make sense to people, that's so small to me."

Wow, a zinger from Mayer to his fans.

Must mean he either doesn't care about them - or does care about the older sister of Ashlee Simpson a whole bunch.

Mayer was most recently quizzed by Ryan Seacrest about Simpson on the red carpet at the Grammy Awards. He answered the American Idol host in Japanese and suggested, "Find a Japanese person and decode it."

The translated answer? "She's a lovely woman and I'm glad to be with her."

But is that still the case, now that Jessica has dyed her famous blonde hair a gross redish brown? We assume so.

After all, Mayer better keep saying the right things - unless he wants Crazy Joe Simpson to beat him down with a tire iron.
