Katie Holmes and Tom Cruise are divorcing

It seems that we are ending the week with a bang, at least as far as huge gossip goes! One of the biggest Hollywood couples around is calling it quits: Tom Cruise and Katie Holmes. Yes, TomKat is officially over. Katie Holmes filed for divorce yesterday.

I have to be honest -- I didn't see this one coming. Without question, this is the biggest celebrity break-up of the year (so far). What happened? A recent report suggests that Scientology might be one reason.Obviously whenever A-list celebrity couples split, speculation is rampant about why, and given the incredible attention paid to Katie Holmes and Tom Cruise over the years, I'd say it's reached def-con level attention today. Everyone wants to know what's going on, and all sorts of crazy stories get circulated. It's just the nature of the gossip beast, I suppose.

Here's the basic facts: Katie Holmes filed for divorce on Thursday, citing the ever-popular "irreconcilable differences." That tells us absolutely nothing. Holmes' attorney says it's a "personal and private matter," blah blah. A rep for Tom Cruise says the actor is "deeply saddened" and wants "privacy." Guess what, Tom? You're not going to get it!

Obviously there's way more going on here, and as usual, TMZ is on the case. Apparently, Katie Holmes is seeking sole custody of six-year-old Suri, and Tom Cruise was totally "blindsided" over the situation. You can bet Tom's lining up some big-time lawyers. My gut tells me this is about to get seriously nasty.

There's more, though: TMZ also cites sources as saying that the main problem that prompted Katie Holmes to file for divorce is the Church of Scientology. Gee, that's shocking, isn't it? We've been reading all sorts of nutty Scientology-related stories about these two for years...and she's just now had enough? This isn't about her -- it's about Suri, apparently, and Katie's fears "...that Tom would drag Suri deep into the church." And that, folks, is the gist of what's going on, I suspect.

Is anyone else a bit shocked that Tom Cruise and Katie Holmes are divorcing? I figured that by this point, Katie was in this for the long haul and by all reports, so did Tom.
