Guy Ritchie has reportedly sought advice from Fathers4Justice, the protesters famed for scaling public buildings in superhero outfits, about the custody fight with Madonna over their son.

The film director, 47, is said to have contacted the fathers' rights group through his representatives for a "jargon-free rundown" of where he stands over access to Rocco, 15.

Rocco left Madonna's tour last December to go and stay with his father in the UK, according to reports.

The singer, 57, and Mr Ritchie are now thought to be locked in a legal battle over custody of Rocco. Madonna appeared to aim a rant at Mr Ritchie at a concert in Nashville, Tennessee, earlier this year.

Matt O'Connor, founder of Fathers4Justice, told the Mirror: We offer support to thousands of fathers, including numerous celebrity dads, with their ongoing cases in the family courts.

“Millions of fathers will understand the pain Madonna is going through after being separated from her son, Rocco.

"Fathers have no right in law to see their children after separation and there’s no presumption of shared parenting.

“It is rare, then, for a mother to experience this kind of loss.

"However, there is no justification for publicly denigrating Rocco’s dad. Children need the best of both parents.”

The Independent has contacted representatives of Mr Ritchie for a comment.
