Sam Clafin and Lily Collins's Love, Rosie has debuted its first trailer and poster through Digital Spy.

The romantic comedy sees the pair play Alex and Rosie, two best friends who plan to move to the US together to attend university. The pair's lives change dramatically over the course of the next 12 years but they're still able to preserve their friendship.

The first-look trailer sees Claflin's character suffer a classroom embarrassment after admitting to losing his virginity to Rosie over MSN Messenger, while the below poster asks fans to share their awkward moments on social media through #LoveRose.

A second trailer, following Collins's character Rosie can also be seen above.

Tamsin Egerton, Christian Cooke, Art Parkinson and Jaime Winstone co-star in the film, which will open in cinemas this October.
