Diggy Simmons, son of legendary Run DMC rapper Rev.Run, is set to walk in the same the Adidas footsteps as his father after being signed up by a record label.

The 15 year old inked a deal with Atlantic Records one day after his birthday following his 13-track mixtape being posted on his blog.

More than 100,000 people downloaded the album from the site but his famous father - known for songs including My Adidas which helped to popularize the brand's footwear - said he knew little about his son's plans.

"I thought he needed help. He just ran off and started doing it himself," Run said.

He added that all he did was watch it happen as Diggy created a hype on the Internet on his own.

Rev Run and his family are the stars of MTV show Run's House, with the seventh series of the show currently being recorded.
