Chris Martin's father has just opened up his son's high profile split with wife Gwyneth Paltrow.

Anthony Martin says that he feels great sadness over the "conscious uncoupling" of the no-longer couple, especially in regards to his grand kids Apple and Moses.

"It is sad and upsetting but they are still great mates," said the former magistrate about the couple, who announced their break up via GOOP on Tuesday.

"If you are married you know you have good days and bad days. But it is all very amicable between them."

The 73-year-old refused to comment on infidelity claims alleged on both parties. However the grandfather said, "It is sad because there are our grandchildren."

When the publication asked about Gywneth's much buzzed-about-term, "conscious uncoupling," the 73-year-old laughed and then brushed it off, saying, "It's all in the statement."

And quite a statement it was!
