And even though most celebrities are keeping their mouth shut for the sake of their social safety, a few have lent their opinions to the Twitterverse!
Joan Rivers: "Tom & Katie are divorcing. This is the most talked-about separation in Hollywood since John Travolta's ass during a massage."
Jason Biggs: "I guess renegotiations fell apart. Shame. I would've liked another couple seasons of "TomKat"."
Michael Ian Black: "TOM CRUISE I WILL MARRY YOU!!!"
Al Yankovich: "Sorry to hear that Tom Cruise's marriage has jumped the couch."
Patti Stanger: "So sorry to hear TomKat split. Feel more sorry for Suri. Definitely one of the more interesting romances."
Loni Love: "For Katie Rock of Ages was the last straw!!"
Nigel Lythgoe: "I am upset for #KatieandTom"
