It seems that breakups in Hollywood are a dime a dozen, but some celeb splits come out of the woodwork to really shock us.
Wednesday's news that Catherine Zeta-Jones and her longtime hubby, Michael Douglas, were separating comes after years and years of both parties publicly praising the other as a supportive partner.
"Catherine and Michael are taking some time apart to evaluate and work on their marriage," a rep for the actress said in a statement to E! News.
However, it's important to note that the Oscar-winning spouses have yet to file for divorce or formal documentation with the court announcing a legal separation.

And they're not alone. Everyone was stunned when news hit that Susan Sarandon was splitting with her partner of 23 years, Tim Robbins.
Not to mention the absolutely media frenzy that occurred when Brad Pitt and Jennifer Aniston announced that they were getting a divorce.
Even the couple that reconnected each year to creatively renew their vows to one another, Heidi Klum and Seal, managed to split after almost seven highly publicized years of marriage.
Let's take a walk down memory lane and review some of the Hollywood splits that completely caught us off guard.
