At the Los Angeles-area stop of [artist id="510062"]Lil Wayne[/artist]'s [article id="1605400"]I Am Music Tour[/article] -- which also features [artist id="1746119"]Keri Hilson[/artist], [artist id="1904930"]Gym Class Heroes[/artist], [artist id="2561902"]Gorilla Zoe[/artist] and [artist id="1998098"]T-Pain[/artist] (recently recovered from his, er, [article id="1608049"]golf-cart accident[/article]) -- Weezy and Hilson indulged in some mature-audiences-only flirting that had the crowd shrieking with excitement.

A video posted on Wayne's blog shows the pair grinding playfully while performing "Turnin Me On" (from Hilson's just-released debut LP, [article id="1607603"]In a Perfect World...[/article]) at the Gibson Amphitheatre in Universal City, California, on Sunday. After the song ends with Hilson singing the line, "... recognize a real woman," Hilson takes a moment to talk to the crowd about Wayne.

"I don't know about y'all, but he's definitely turning me on right now!" she says. "That's right -- Wayne, he knows how to recognize a real woman."

She then moves behind him -- standing a good six inches taller than the diminutive MC -- reaches over his shoulder, lifts up his shirt and says, "Let me tell y'all something you might not know: Ain't a damn thing lil about this Wayne!"

As the crowd shrieks its approval and Hilson begins walking offstage, Wayne gives her a playful swat on the butt. She sings, "Now wait a minute!," then laughs and says "Bye baby!" Wayne says "Bye baby!" before roaring "Keri Hilson, y'aaaaaaall!"

The pair also performed the song -- with more tame flirting -- on "Jimmy Kimmel Live" Friday night.

Lil Wayne's tour continues into April, with stops on the West Coast and Hawaii before heading into the Midwest. At press time, Weezy's oft-delayed forthcoming rock album, [article id="1603446"]Rebirth,[/article] still did not have a confirmed release date.
