Liev Schreiber believes he and Naomi Watts will always be ''very close''.

The 'Ray Donovan' actor and the 48-year-old actress split up in September after an 11-year relationship, but he insists they will always be ''together'' because they are parents to sons Alexander, nine, and Samuel, seven.

Asked on 'CBS This Morning' if the change in his personal life is scary, he said: ''Yeah. Of course it is. But, you know, we're parents together so we'll be together for the rest of our lives no matter what and, um, we're very close. Hopefully, that never changes and I don't think it will.''

And the 49-year-old star joked he is currently too busy working on his Broadway show 'Les Liaisons Dangereuses' to go on a date with anyone knew at the moment.

Asked by presenter Gayle King if he wants her help getting a date or if he is OK at the moment, he referred to Cecile Volanges, who his character in the play seduces, and joked: ''Yeah. I'm busy with the 15 year old.''

While this is the first time Liev has spoken out since his relationship ended, Naomi recently said she is in a ''good place'' following the split.

''I feel I'm in a good place in my life and I want to make sure my kids are healthy; my kids are happy and things are going to go well. Those are my hopes for me and for all of us.

''I feel like change is always scary, but that's only because transition for anyone is new and you wonder how things are going to go.''

Following their split, Naomi was spotted in the audience at 'Les Liaisons Dangereuses' and she believes it is vital for their children that things stay cordial between them.

She previously said: ''He's the father of my kids. So it was important to support him.

''I was very curious to see this and all of his work.

''The play is fantastic and really I hope everyone gets to see it because he does some extraordinary work up there.''
