The latest to join the list is Kaley Cuoco - television's highest earning actress recently split from her husband of 21 months, Ryan Sweeting, citing "irreconcilable differences".

Here is looking back at celebrity couples who couldn't do justice to "till death do us part."

Ben Affleck and Jennifer Garner:
This was probably the biggest heartbreaker of the year. When the two stars announced their divorce after 10 years of marriage and three children, the rumour mills went berserk, the latest being that Garner is pregnant with Affleck's fourth child.

Jon Hamm and Jennifer Westfeldt: Lead star of the now-iconic show Mad Men, Hamm split with his girlfriend of 18 years, actress-screenwriter, Jennifer Westfeldt last month. The two seem to have parted ways amicably with Hamm crediting Westfieldt's support as the reason he beat his alcohol abuse. He also thanked her post his Emmy win very recently.

Megan Fox and Brian Austin Green:
This couple had a whirlwind of a romance. The two got tongues wagging when they first got together. Reason? Megan was 18 while Brian was 30. The duo got engaged after two years of dating but split soon after, only to get married in a private ceremony in Maui in 2010. They welcomed two boys to the world. But alas, after 11 years of being together, and five years of marriage, the two have split again.

Blake Shelton and Miranda Lambert:
