Jason Segel and Alexis Mixter

The Forgetting Sarah Marshall actor and his artist girlfriend split in April after eight years of dating.

Mixter announced their split in a lengthy Instagram post, writing: "The depth of our bond was something I could never have anticipated. I’ve never spent so much time with another person, grown so much alongside someone else, laughed so much, cried so much, shared so much.

"It is odd to write about the end of a relationship, especially when the friendship that still exists is so full of life…. Announcing a breakup on social media is a strange feeling. Some won’t understand why it is necessary and that’s okay. Having a public romantic relationship is not easy.

"Ending one feels like navigating a road that doesn’t even exist. We are private people when it comes to our personal lives and I intend to keep it that way…. Thank you, J for being my best friend…. I will never stop cheering you on with every cell of my body. I will never stop loving you unconditionally.''
