Reunited! Kim Kardashian and Justin Bieber

Back together at the Do Something Awards - but they're matchmaking for other people

They joked last year that they were girlfriend and boyfriend before despite the 13 year age gap - and Justin Bieber and Kim Kardashian were reunited last night.
However, in a neat twist, it now appears that the pair are in the business of matchmaking for other people.
Kim, 30, and Justin, 17, were back together at the Do Something Awards last night and were pictured having fun together.

However, it seemed the pair truly did have ulterior motives, with Kim tweeting afterwards: 'At awards w @JustinBieber! Just met his friend, wonder if that's who he wants 2 set Kendall (half sister Kendall Jenner) up w LOL'
Last year, the pair declared their love for each other in a series of jokey Tweets after meeting at the White House Correspondents Dinner in May.
They then went on to shoot an ad campaign together in the Bahamas then did a 'Mrs Robinson' style photoshoot for Elle magazine - causing uproar amongst the teen's fans, the Beliebers.

However, Kim is now happily spoken for, and is tying the knot next week with Kris Humphries, while Justin is dating Disney star Selena Gomez.
Kim had taken time out from her hectic wedding preparations to squeeze in her appearance at the Do Something Awards and poured her curves into a form-fitting white gown.
She shared the spotlight with former Disney star Demi Lovato, who also went for the same colour scheme as Kim.

Transformed: Later inside the event, Demi slipped into a floor-length flowing gown to perform onstage

But while Kim put in a rather demure turn in her floor-length outfit, Demi put her flesh very much on show in her short and low-cut design.
The duo posed together at the Los Angeles event, before making their way inside the Hollywood Palladium.
Later Demi took to the stage to perform, transforming into a full-length ensemble, while Kim made an on-stage appearance and mingled with the fellow guests, including Justin Bieber.

Other stars in attendance included model Tyra Banks, who also had her photograph taken, and Kristen Bell, who brought along her husband Dax Shepard.
Bell, 31, dazzled as she made her arrival in a short asymmetrical gown and smooched before the cameras with Dax.
She is also one of the guest presenters of the night with main hosting duties going to Glee star Jane Lynch, who was at the helm last year too.
