Ashton Kutcher is currently "unreachable", according to his 'Two and Half Men' co-star.

The actor - who recently split from wife Demi after six years of marriage, following reports he cheated on her - has not been in contact with his work colleagues for a while but Jon Cryer can understand why.

Jon - who has been nominated for Outstanding Performance by a Male Actor in A comedy Series at the Screen Actors Guild (SAG) award - said: "As you could imagine, Ashton is off the grid and completely unreachable for a couple of weeks, so I will text him repeatedly saying, 'Dude, I got nominated.' We'll see what his reaction is when I can finally reach him."

Ashton replaced Charlie Sheen in the series - after he was fired from the show - but Jon admits he will always be grateful to his former co-star.

He told 'E! News': "If I win, Of course, I am going to thank Charlie. When they gave me a Star On The Hollywood Walk Of Fame, I thanked him.

"I'm still grateful for the guy. We had a great working relationship, and I still wish him nothing but the best."
