A rep for the couple confirmed their separation on Wednesday evening (28 May), saying the break-up was amicable and their focus now is on their baby son, who was born in July 2013.
The statement to People read: "They both love and respect one another and will of course remain committed to co-parenting their son. This is a mutual decision and the two remain close friends."
Evan, 26, and Jamie, 28, met on the set of 2005 music video 'Wake Me Up When September Ends' by the band Green Day. After a brief period apart, they went on to marry seven years later in a private ceremony,
The notoriously private couple welcomed their first child last July but have kept details about him away from the public eye, including his name.
"People obviously know I was pregnant—can't hide that—so I have no problem talking about the baby and that we're doing really well," Evan told The Daily Beast last year. "But I haven't released his name. I've done my best to keep his picture from being taken, just because kids don't really have a choice in the matter."
Evan, who has more than 200,000 followers on Twitter, has yet to publicly address the separation, but shortly before the news broke she tweeted: "Twitter break for a while...to be continued."
Her Twitter bio still reads Mrs Bell.
