Like Jason and Kylie

This is just too cute. The Wanted Nathan Sykes decided to lend a hand to his girlfriend Ariana Grande by performing a duet with her onstage.
It was a bit like Grease, without the leather jackets.

Just in case you didn't know, the unbelievably beautiful brunette is a singer and actress in her right across the pond - 20-year-old Ariana even starred in a cute sitcom called Victorious.

The Baby I singer was joined by her lovely beau at the secret gig at Rise nightclub in Leicester Square - and although there was a bit of an awkward hug at the end, it went rather well.

Nathan features on Ariana's track Almost Is Never Enough, scroll down for listen.

Closer than close

Later on Nathan, 20, was rewarded with a big smooch from his leggy lady as they dined out post gig.
Ariana has revealed her next tune will be about her popstar boyfriend, after her latest single starring Big Sean called Right There.

She told Notion Magazine: "I’m the happiest I’ve ever been and I’m learning a lot of lessons from this relationship. I think that’s beautiful and it’s something that should be expressed.

"I’m always going to be as honest. I want to be. Music is the greatest form of self-expression.
"You best believe I’m going to be writing about him!"
