Something big happened that forced Russell Brand to pull the trigger on his divorce from Katy Perry -- and it happened very recently ...
And, the biggest celebrity train wrecks of 2011 -- you'll never guess who makes the list...
Katy Perry and Russell Brand have not decided to end their marriage ... this according to multiple sources directly connected to the couple.
We are told, however, that they are having problems, but our sources say it has nothing to do with reports of a big, blowout argument ... because we're told no such argument ever occurred.
Russell was spotted out in London today ... again without his wedding ring. He wasn't wearing it yesterday either.
As for Katy not wearing her ring, we're told it's no big deal. As one source notes, she doesn't wear the ring when she performs ... and it has nothing to do with Russell or her marriage.
One of our sources says it's clear Katy and Russell are "dealing with something," but divorce court is not the end game ... at least not yet.
12:00 PM PT: Go figure ... Russell has filed for divorce.
Rumors that Katy Perry and Russell Brand are calling off their marriage have just been fueled by explosive new photos ... of Russell in London ... NOT wearing his wedding ring.
The "Get Him to the Greek" star was in the West End earlier today, half a world away from his wife, who has been vacationing in Hawaii ... wearing nothing but bikinis.
The couple spent XMAS 7,000 AAdvantage miles apart. They tied the knot just over a year ago last October.
