Justin Bieber and Selena Gomez do battle for internet award

Justin Bieber is going up against his girlfriend Selena Gomez for an internet award recognising the best social media users.

The teenage sweethearts, both avid Twitter.com fans, have made the shortlist for the Shorty Awards, which honour the producers of the best content across social networking sites such as YouTube.com and Facebook.com.

The duo is going up against Demi Lovato and Miley Cyrus to be named Celebrity of the Year at the upcoming ceremony on 26 March (12).

The Vampire Diaries star Ian Somerhalder, Harry Potter's Tom Felton, and Kevin Jonas are gunning for the Best Actor trophy, while Gomez, Cyrus and Indonesian star Agnes Monica are up for Best Actress.

Somerhalder has racked up another nod in the Green category for eco-aware social media users, while his cult vampire series is nominated for Best TV show with Pretty Little Liars and The Glee Project.
