Video Proof of Tom and Katie's Unbridled Passion

Here's all the proof you need that Tom Cruise and Katie Holmes are as romantically on fire as they were the day he proposed to her atop the Eiffel Tower.

At a benefit the other night, Katie sang "Whatever Lola Wants (Lola Gets)," slithering around her hubby as he panted, put his face near her crotch area, and even fell to the ground in a mock faint before planting a big old kiss on her face as the crowd went wild.

Not since Tom jumped on Oprah's couch has there been such a public act of sexual devotion between these two wacky lovebirds.

But need I remind you that that particular song is from Damn Yankees?

The show about selling your soul to the devil?
