Dappy has enlisted the help of legendary rocker Brian May for his second solo single 'Rock Star'.
The N-Dubz star, whose debut 'No Regrets' was a No. 1 hit in September last year, premiered the video for 'Rock Star' today.
Queen star May is thought to have teamed up with the behatted rapper after becoming a fan of his previous record.
Dappy has joked that he was banned from meeting Little Mix, mentored by his cousin Tulisa Contostavlos, because of his womanising reputation.
N-Dubz released their Greatest Hits set last November.
