The latest celeb to make an appearance on Guys with iPhones (site nsfw) is New Kid on the Block Jordan Knight.
Looks as though that birthday boy kiss Donnie Wahlberg gave him a few weeks ago was something to which Knight was accustomed.
Matt Rettenmund at Boy Culture writes: "Kyle Wilker, 27, tells the rag Jonathan realized he 'preferred guys to girls' after dating Tiffany. (Sorry, Tiff. Ouch.) 'We had a wonderful relationship. I was in love with him and I believe he was in love with me.' They met at a bar Kyle was working at on Fire Island...there are so many hints in that sentence that this would end, and then end up in the Enquirer."
The crowd went nuts at a New Kids on the Block concert Wednesday night in L.A. when Donnie Wahlberg decided to present Jonathan Knight a big wet kiss for his birthday.
Watch it, AFTER THE JUMP...
