There were burgers and fries, chicken fingers and mashed potatoes and cupcakes galore at Sunday night's Tom Cruise- and Katie Holmes-hosted shindig to welcome BFF's David and Victoria Beckham to Los Angeles, but the only thing several of the big names at the bash wanted to nibble on was each other.

The London Daily Mirror says the guests of honor spent the evening "smooching like teenagers," with the squeaky-voiced soccer stud at one point pulling his hollow-cheeked but top-heavy wife close as they danced and whispering, "I love you so much."

They weren't the only duo overdosing on mushiness.

Will Smith and Jada Pinkett Smith, who co-hosted with the Cruises, shook their groove things on the dance floor, with the actor demonstrating his bendiness by doing the splits (per Us Weekly).

At the end of the evening, Will, who was kitted out in a shiny silver suit seemingly from the new "Lost in Space" couture line, chivalrously carried his pint-sized wife out of the party.

Meanwhile, Jim Carrey managed to brush his unflattering shoulder-length mane out of his face long enough to give girlfriend Jenny McCarthy a tonsillectomy on a sofa.

"It looked like they should have got a room," a spy tells the paper of the comedic couple, "but they didn't seem to care."

As for Tom and Katie, they did that PDA thing they do so well, holding hands and snuggling during the night before busting a move.

The paper says that during a particularly saucy number, the punch-line-prone actor dropped to one knee and strained his neck gazed up "adoringly" at the high heel-clad Holmes.

Cruise also managed to call to mind a time when his public image wasn't so tarnished and conspiracy-crammed by getting funky to -- yep, you guessed it -- Bob Seger's "Old Time Rock & Roll."

Thankfully, he decided against trying to achieve tightie-whitie verisimilitude and doffed only his jacket during the "Risky Business" homage, although Us reports he did copy one of his bygone character's moves by getting on his back and shimmying with his legs in the air.

Go on, say it: Yeeesh.

But the hoofing hijinks didn't end there. Tom, who was snapped looking extra moist as he cut a rug with his butt-shaking missus, also took a cue from Smith by doing four -- yes, four -- "breakdance-style splits" (per OK!).

Not everyone was impressed, however. The Los Angeles Times says the crowd was "gawking in amazement" at Cruise's moves, with one onlooker zinging, "What is this, his bar mitzvah?"
