Is this film being re-released or something?

I was checking out future releases at work; and this film popped up under the title 'Because of a Boy: You'll Get Over It'

Now I love gay cinema, so I thought I'd check it out further online. I couldn't find anything under the exact title mentioned, but I found this instead. With the exact same actors and and plot - which pretty much answers my question; but does anyone know why they are re-releasing it?

Amazon and where I work (HMV) are bother releasing it in June: http://www.amazon.co.uk/Because-Boy-Youll-get-Over/dp/B0074I149W
