Movies about bestfriends falling in love?

Like the "F the Prom" and that kinds of movie. Where bestfriends since long time ago fall in love. Preferably new movies (2013 and up)

Zack and Miri make a porno

Just Go With It (2011 but very good movie)
Napoleon Dynamite (2004)

To this day I've still only seen half the film – I've got to rectify that – but I love it .

It was definitely funnier than I'd expected

There's no PROM involved, but "made of honor" was worth watching
