Now, alongside judges Amanda Holden , Alesha Dixon and KSI, Bradley has appeared at Blackpool's Winter Gardens as the hunt for some new stars begins. Fans lined the streets to celebrate the show's 20th anniversary, and Bradley shared a behind-the-scenes clip from his first day on set , showing him loving his big moment.
