David Walliams joked that Prince Harry is a "big Peter Andre fan" after he invited the royal to join him at one of the singer's concerts.
The Britain's Got Talent judge pulled out a leaflet promoting Andre's upcoming UK tour dates as he was introduced to Harry at the Royal Albert Hall.
Walliams was hosting the Responsible Business Awards gala dinner at the venue in central London, which was being attended by the Prince of Wales and his sons, the Duke of Cambridge and Prince Harry.
"Nobody wants to come with me," Walliams said to Harry after picking up the leaflet from the Royal Albert Hall foyer.
After meeting the Prince, the Little Britain star joked: "He's a big Peter Andre fan."
Some 1,400 guests gathered for the event which was hosted by Walliams and presenter Natalie Pinkham and featured performances by the Military Wives Choir and poet George Mpanga.
Charles, who is president of the Business in the Community (BITC) charity, gave a keynote speech and urged business leaders to create more training and job opportunities for former military personnel.
He said: "I want to look at a situation, which is just as big a concern to my sons as it is to me, where fortune very often does not favour the brave.
"And that is in the opportunities available to our troops when they return home and seek employment outside the armed forces. Loyalty, integrity, teamwork and the ability to work calmly and with discipline and good humour under intense pressure are qualities that any business must surely value highly.
"However the transition is by no means easy, and we should not pretend it is, even for the able-bodied. For those who have been wounded, of course, the difficulties are greater still."
The royals were introduced to Mr Mpanga, known as George the Poet, and members of the Military Wives Choir before they left the venue.
Mr Mpanga said: "William was asking if I was a rapper previously, which I was. He must have an ear for rap music.
"He said there was so much gravitas and meaning behind what I was saying. It was very humbling."
