Professor Green has thanked Lily Allen for her support during his rise to fame.

The rapper – real name Stephen Manderson – became good friends with Allen after he asked her via Facebook to feature on his new single ‘Just Be Good To Green’, and admits the first time he performed the track with her was “the maddest day” of his life.

He told The Sun: “She couldn’t be around for my set at Glastonbury, but we did the Wireless festival in London this month, which was phenomenal. It was nuts. It was the first time we had performed ‘Just Be Good to Green’ together live. It was the maddest day of my life.”

“She’s been incredible to me. There are very few people I have met in this industry that I count as real friends. And with her it’s definitely reached that.”
