Madonna's son David Banda is selling songwriting sessions for £3,900 ($5,000)

He posted on his Instagram account: "Write a somg [sic] with me in person, limited time only from 8-28 Sept!"

He added: "To write a song, excuse my writing."

David has also been selling virtual guitar lessons online.

Meanwhile, David recently claimed he had been "forced to scavenge for food" since moving out of Madonna's house.

Asked how he felt about living on his own during an Instagram Live, he said: "I love it. I'm not on my own, I've got my girlfriend. But I love it. It's lovely to experience it being nine o'clock at night, me being hungry and realising that I don't have enough money to get food and scavenging. It's fun to be young!"

David also used his brief update to his followers to confirm that the 'Material Girl' hitmaker - who was initially married to Sean Penn from 1985 until 1989 and then to Guy Ritchie 2000 until 2008 - is not currently single and is seeing someone, but did not reveal his identity.

He said: "Truth be told, she's not single. She's dating a guy?.?.?.? That's her life. She'll do what she wants to do."
