There's No Changing Steven Tyler's Stripes

Feb. 4, 2011— -- Just like a tiger, Steven Tyler isn't about to change his stripes.

A day after Fox's (faux?) apology for his "outrageous behavior," the freshman judge on "American Idol" was back to his old tricks.

This time, Tyler ogled contestant Heidi Khzam. While she performed a mesmerizing belly-dance routine, Tyler turned into a human beat box, complete with "ah's" and 'um's." Randy Jackson joined in, rapping the beat on the table. Jennifer Lopez sat in the middle, a wide smile plastered on her face, leaving us to wonder what she was really thinking.

Then, after crowing like a rooster, Tyler seemed to remember this was a singing competition and turned serious. "You got something you could sing for us real quick?" he said to Khzam.

As it turned out, Khzam made it through to the next round.

For the most part, Thursday's Los Angeles auditions focused less on the talented and more on the terrible:

Tynisha Roches may have been the first woman to chase Jackson around the room as she screeched half-remembered lyrics in an ultimately futile attempt to persuade the judges.

Matt "Big Stats" Frankel claimed to be a music producer who helped "bunches" of artists, including Chaka Khan, while proudly displaying his Los Angeles Transit bus pass, but his audition had little to do with singing.

There were a couple potential shining stars. The affable Gutierrez brothers, Mark and Aaron, won over the judges with a soulful rendition of "Lean on Me."

"It was God-like, the way you guys sang," Tyler told them. "After today, it was just what we needed."

Karen Rodriguez, who auditioned via MySpace and was then flown to LA, also impressed the judges with "You Give Good Love." Lopez was especially moved after Rodriguez reminded her that they had met before on MTV's "TRL," where Lopez told her she had a good voice.

"You're going to make me cry," Lopez said.

But the moment that late-night comedian Jimmy Kimmel was talking about last night belonged to Tyler. He featured Tyler and belly-dancing contestant Khzam in a segment called "The Steven Tyler Creepy Leer of the Night."

"That's why he's known as the world's horniest beat box," Kimmel joked.
