Speaking to the Daily Star Sunday, Frankie revealed he was given £1,000 for the set-up photographs by the Newcastle star's management.
“Holly certainly got her money’s worth – in publicity and apparently in the bedroom too," a source told the newspaper.
Speaking to the tabloid himself, Frankie said he regretted taking the money.
“I got a grand off Holly’s agent for kissing her in the street. They gave me the money that night for doing it. I just did it because I was pissed, to be honest," he said.
He added: “The next day I regretted doing it.
“I know a lot of celebs set up pap shots on a regular basis and make money from it but I’m not normally into that. I just did it the once.”
Frankie, who was booted out of The X Factor last November, recently told TellyMix had he was hoping to put his drinking days behind him and focus on a career in music.
