Paltrow announced her "conscious uncoupling" with Martin in 2014 after ten years of marriage. She has since moved on with 'Glee' co-creator Brad Falchuk, but still keeps in touch with her ex-husband. She said he's like her brother after their split.
Martin is currently with 'Peaky Blinders' actress Annabelle Wallis.
