Questionable arrivals at the TomKat wedding

After seeing some of the photos of who is arriving for this shindig, I got to wondering: Why the hell are some of these people there? Like Jenny McCartney and J.Lo? Huh? Am I missing something? I mean, even Oprah didn't get an invite and TC trampled all over her couch. I highly doubt some of these folks hang out at the Telluride manse and exchange L.Ron-isms, do they? God, I hope not, I like Jenny McCartney and Jim Carrey way too much for them to turn out to be freakin' Scientologists. Well, luckily for me, TMZ has gotten to the bottom of this...

Who knew that TomKat and J.Lo were such bosom buddies? Not us -- maybe not even them.

Given that we thought the guest list at the Cruise-Holmes nuptials in Italy seemed more like a Fellini film, or an episode of "The Surreal Life" -- Marc Anthony? Jenny McCarthy? Jenna Elfman? -- we tried to break down exactly what some of these people were doing all the way over in Bracciano, so far away from home. It should make for some awkward moments during the dinner hour.

Several of the guests -- John Travolta, Elfman and her husband Bodhi, and Leah Remini -- are members of the Scientology tribe, so that makes sense. But what about J. Lo? It turns out that Lopez and Remini are close pals ... and remember that Remini was the first celeb to cop to a Suri sighting, so we know she's in the inner circle.

Now we're pretty sure that Jenny McCarthy and TomKat haven't worked together on anything recently, but J-Mac's squeeze, Jim Carrey, used to go out with Renee Zellweger, who, of course, was Cruise's co-star in "Jerry Maguire." No word from Carrey's rep on whether this rather tenuous connection is the precise reason for his attendance.

Perhaps J.Lo's husband Anthony said it best in a toast he reportedly gave last night in the bar at the wedding hotel in Rome: "To life, to the occasion, and to new friends." Or, as the case may be, complete strangers. [TMZ]
