Backstreet Boys singer A.J McLean has joked that Gangster Squad actor Ryan Gosling is more than welcome to join his band.

The 35-year-old singer and The Notebook star used to live in the same apartment block in Orlando, Florida before they became famous and A.J joked that Ryan could still become the sixth member of his boyband.

However, Ryan recently claimed that the musician never answered his calls once the Backstreet Boys became famous.

Speaking to TMZ, McLean said: ''I just want to say to Ryan, I am so sorry I didn't call you back. Dude, first of all I don't even have your number. When I see you at the gym, you know which gym, let's finally exchange numbers and if we ever need a sixth Backstreet Boy I will call you. He can sing, Ryan can sing his ass off.''

The Incomplete singer went on to praise Gosling's many talents, adding: ''Not only are you a talented actor and a handsome man but a great singer. My wife is obsessed.''
