With Naomi Watts and Liev Schreiber announcing separation after 11 years of togetherness, rumour mills are once again set to go on an overdrive. They aren't the first celebrity couple of the year who shocked their fans by parting ways. Just last week, Angelina Jolie and Brad Pitt filed for divorce, ending their 12-year-old relationship that began on the sets of Mr. & Mrs. Smith.

Naomi and Liev, who have two children -- Alexander (Sasha) Pete Schreiber and Samuel Kai Schreiber -- together, confirmed their split in a joint statement to People magazine. It reads: "Over the past few months we've come to the conclusion that the best way forward for us as a family is to separate as a couple."

Amber Heard-Johnny Depp, Sharon Osbourne-Ozzy Osbourne, Lady Gaga-Taylor Kinney, Drew Barrymore-Will Kopelman and Jennifer Lopez-Casper Smart are among some of the surprising celebrity break-ups of 2016.
