David Schwimmer looked downcast on a solo outing just days before he and his wife announced they are taking time apart.
The 50-year-old actor has split with 31-year-old Zoe Buckman according to Daily Mail.
The couple - who married in June 2010 - confirmed to Us Weekly on Wednesday that they are working out their future.
'It is with great love, respect and friendship that we have decided to take some time apart while we determine the future of our relationship,' the pair told the publication in a statement.
The couple - who have five-year-old daughter Cleo together - added: 'Our priority is, of course, our daughter's happiness and well being during this challenging time, and so we ask for your support and respect for our privacy as we continue to raise her together and navigate this new chapter for our family.'
The Friends alum and British photographer Buckman have been together for more than 10 years.
They met when Schwimmer was directing the 2007 romantic comedy Run in London.
She relocated to Los Angeles to be with the actor and the pair tied the knot in June 2010. It is the first marriage for both.
The People v. O.J. Simpson: American Crime Story actor and Buckman often kept private about their relationship.
Schwimmer has previously spoken of how difficult he finds being famous and admitted stardom impacted on his relationships with other people when he was first adjusting to life in the public eye.
He told THR's Awards Chatter podcast: 'It was pretty jarring and it messed with my relationship to other people in a way that took years, I think, for me to adjust to and become comfortable with. As an actor, the way I was trained, my job was to observe life and to observe other people, so I used to walk around with my head up, really engaged and watching people.
'The effect of celebrity was the absolute opposite: it made me want to hide under a baseball cap and not be seen. And I realised after a while that I was no longer watching people; I was trying to hide.
'So I was trying to figure out: How do I be an actor in this new world, in this new situation? How do I do my job? That was tricky.'
