Tom Cruise was called out ... CHALLENGED ... on the dance floor at the wedding of a BILLIONAIRE'S SON -- but after the clash ... only one man walked away victorious.

Tom and Katie were in Palm Springs this weekend celebrating the wedding of Sandy Modic and David Ellison.

David is the executive producer on "Mission Impossible -- Ghost Protocol" ... and also happens to be the the son of Oracle CEO Larry Ellison ... the 3rd richest man in the United States.

Tom was just hangin' out when one of Ellison's friends declared DANCE WAR ... and Tom accepted.

So, we gotta ask ...

Cops swarmed Tom Cruise and Katie Holmes' block in Beverly Hills yesterday -- armed with a full arsenal of heavy artillery, including assault rifles -- and we're told ... it was all over some missing tools.

Law enforcement sources tell TMZ, cops were called for an alleged burglary at a nearby construction site -- on the same block as T&K -- and police descended in full force.

We're told cops paid a visit to the surrounding homes -- including the Cruises' -- but came up empty.

It's unclear how much was stolen in the heist -- or whether Tom and Katie were home at the time of the search.

Tom Cruise really put the squeeze on his wife Katie Holmes last weekend in L.A. -- copping a SNEAKY feel of her ass at a Katy Perry concert -- and TMZ has obtained the hands-on footage.

Katie got the pat-down Sunday night at Nokia Theater -- and we're told, Tom's hand remained steadfast for most of KP's performance.

Side note: never invite Tom and Katie to your party ... we're told the couple's entrance delayed the concert a solid 15 minutes.

And watch closely -- standing next to the touchy-feely couple is none other than Katy Perry's hubby ... Russell Brand. What a handful.

Tom Cruise showed off his hairless, ripped pecs and abs while shooting a stunt for "Mission Impossible 4" in Prague on Wednesday.



The 48-year-old has really built up an amazing body of work.

Tom Cruise was secretly videotaped as he spilled his guts in Scientology confessional sessions, and those tapes became fodder for Scientology cocktail party humor ... this according to a high-profile and former high-level member of Scientology.

Mark Rathbun says in his blog, he recorded Cruise during the confessional sessions and Scientology guru David Miscavige read the transcripts at parties, "joking and laughing" at them.

Rathbun says the video was "well-concealed" in the VIP auditing room, per orders of Miscavige. Rathbun says Miscavige ordered him to prepare transcripts of the sessions. Then, according to Rathbun, Miscavige would hold late night whiskey parties, reading the transcripts and laughing out loud.

The nature of Tom's alleged confessions were not disclosed.

Tom Cruise unleashed his inner Broadway star this weekend -- stage-diving, dancing and even kissing his wife, Katie Holmes, during a performance of a "Damn Yankees" song for a charity event.



It all went down during a performance of "Whatever Lola Wants" at the "A Fine Romance" benefit gala in L.A.

Before you get all in a huff, it's a famous line from "Jerry Maguire."



Sitting courtside at the Lakers game, Tom Cruise said hello to both Chris Brown and Kobe Bryant last night.

Tom Cruise took a break from filming his latest movie to spend a little time in his own personal Porta-Potty, adorned with his character's name.



"You want the deuce? You can't handle the deuce!!!"

Tom Cruise is being sued for allegedly hiring a notorious P.I. to illegally wiretap a magazine editor's phone ... according to documents obtained by TMZ.



The plaintiff, Michael Davis Sapir, claims Cruise, attorney Bert Fields and jailed private investigator Anthony Pellicano conspired to spy on him.

There is a long history between Cruise and Sapir. In 2001, Cruise sued Sapir for $100 million after Sapir claimed to have video evidence that Cruise "engaged in a homosexual relationship." That lawsuit settled later that year. In the settlement, both parties issued a statement saying that no such tape existed.

In the latest suit, filed Friday in L.A. County Superior Court, Sapir claims Pellicano illegally wiretapped his phone during the time the 2001 lawsuit was active.

Sapir claims in the suit that Cruise, Fields and Pellicano were all in cahoots.

Sapir is suing for $5 million, minimum.

Bert Fields tells TMZ, "The allegations are absolute garbage. We did not even hire Pellicano to work on the Sapir case."

No immediate comment from Cruise's rep. Pellicano is in the pokey.

Nicole Kidman refused to answer a Scientology question during an interview for a BBC show -- if you love awkward moments, you should probably watch this clip.



Kidman, who was promoting "Nine" on "The Andrew Marr Show," was asked about her ex-husband Tom Cruise's religion -- which Marr said some people called a "bullying cult." His words, not ours.

Surprisingly, Kidman wasn't game for that Q and immediately shut him down.

Tom Cruise jumped off a six-story building yesterday -- face first -- and lived.



Cruise launched himself off the building for an upcoming movie he's shooting in Austria -- in which he's doing just about all of his own stunts.

During the shoot, Tom is literally dangling on the side of the building, connected only by a few cables.

Then again, he's not your average SP.
