Is Adam Lambert Kissing to Keep Up With Lady Gaga?

Could last year's American Music Awards buzz act be jealous of this year's meat-dress sensation?

Oops, Adam Lambert did it again—kissed one of his bandmates onstage, this time in Tokyo.

Part of us thinks, so what? Lambert likes kissing, and he especially likes kissing bandmates who happen to be men. More power to him. 

But part of us wonders, did he pucker up this time with purpose? Was he trying to out-Gaga Lady Gaga? 

Last fall, after all, it was Lambert who owned the "Did you see that?" question, courtesy—sound familiar?—of his onstage smooch of a (male) bandmate at the American Music Awards.

But this fall, we're all abuzz over Lady Gaga, her meat-wear, and her newly vocal gay-rights efforts, as promoted, in part, by her meat-wear.

So, it is plausible that Lambert was getting a little jealous, a little lonesome for headlines, maybe even a little hungry? 

Yes, according to Beverly Hills psychiatrist Dr. Carole Lieberman.

"When a rival celeb gets attention for their PR stunt, other celebs are driven to steal the attention away, and grab it back for themselves," Lieberman told us via email. "…It is plausible that Adam, known for being irreverent, does not want to be outdone by another singing sensation."

If that's so, then Lambert best see if Bruce Willis' meat toupee is available. The only way to battle Gaga right now is to come armed with your best piece of steak.
