Michelle Beadle -- Doubles Down On Kim K ... 'No Talent, Desperate, Photoshop'

Even MORE shots fired in Michelle Beadle's war on Kim Kardashian ... and it's all on video.

Beadle already blasted the reality star on Twitter last week over the nude shots for Paper Magazine -- and this weekend at LAX, Beadle made it clear she isn't backing off.

"What else is she gonna do? She's got no talent," Beadle said.

"She doesn't have anything else to show off ... so I get why she's doing it."

"And photoshop's wonderful."

So far, no word from Kim on the situation.
