Are billy mack and his manager Joe gay?

Rating: 10/10 (16 December 2005)

Me and my friends loved the movie and have seen it several times, but we always argue over if Billy Mack and his manager Joe are gay. I think so, but my other friend says no. What do you think? My friend says that him and Billy just realized that the went through their whole lives just to realize they are best friends and that sense Billy Mack tells Joe that he's the love of his life. I think they finally realize, after all that time, that they do deeply love each other and at that moment become gay. Another things that leads me to believe this is at the end when Billy Mack brings that girl home in the airport and Joe doesn't even know who she is. I think it's a cover-up for their homosexuality. Any thoughts would be greatly appreciated.
