Nathan Moore, former singer with pop groups Brother Beyond and Worlds Apart, has pleaded guilty to a charge of kerb crawling in central London.
Nathan Moore appeared at Highbury Corner magistrates court on Friday
The 39-year-old from Islington, London appeared at Highbury Corner magistrates court on Friday where he was fined £250 and ordered to pay £50 costs.
"I am really sorry for being here today," Mr Moore told magistrates. "I would really like to close this now."
The former pop singer was arrested on 27 May in the Kings Cross area.
The court heard he approached a woman he thought was a prostitute and requested a sexual favour.
But the woman was actually an undercover police officer.
After riding away on his moped he was arrested by two other officers for soliciting a female.
Mr Moore told magistrates he had considered asking for an adjournment but now wanted "to put this matter away and get it finished".
"I am just going to accept my punishment," he said.
"For me the damage is done and today will add further to the weight of my already heavy burden."
Magistrates considered imposing an Anti-Social Behaviour Order to ban Mr Moore from the Kings Cross area but decided it had been a "one-off" offence.
Outside the court the '80s pop idol told reporters he had wanted to avoid a high-profile trial.
Mr Moore was a member of the pop group Worlds Apart in the 1990s
"Under the circumstances I have been treated pretty fairly," he said.
"I pleaded guilty knowing I am innocent because I am really fed up with the press intrusion."
Working with producers Stock, Aitken and Waterman, Brother Beyond had a number of chart hits in 1988-89.
These included The Harder I Try, which reached number two in July 1998.
Mr Moore later joined Worlds Apart, enjoying success in the UK and France in 1993 and 94.
He now manages pop act Phixx, Eurovision contestant James Fox and former Pop Idol contestant Hayley Evetts.
