Chelsea have signed 14-year-old Leo Castledine from AFC Wimbledon.
The midfielder is the son of former Homes Under the Hammer host Lucy Alexander and ex-Wimbledon star Stewart.
Leo followed in the footsteps of his father when he joined the League One side at the age of seven.
Stewart played for Wimbledon from 1991 until 2000, but the youngster has decided to end his stay with the club after seven years.
The youngster announced the move on Instagram as he shared a photograph of himself signing the Chelsea contract.
