Popstar Chesney Hawkes has sent a message of congratulations to one of his superfans, who's racked up 520 miles on her driveway.

Lesley Dunn embarked on the challenge last December to raise money for Dorset's Monkey World, where her adopted diabetic chimp Bart lives.

Not only has she done the walk solely on her 60-foot drive, she's also done it listening only to the music of Chesney Hawkes and his dad Chip, who was in the band The Tremeloes.

Lesley joined Steve Harris live from her drive as she was about to finish her challenge.
