The Wizards Of Waverly place star showed off her super slim figure in the spangled attire, which featured tiny shorts and a low-cut front.

The singer let the risque outfit do all the talking, wearing her brunette locks out in a natural wave and accessorising with a simple pair of hoop earrings.

As always Selena used her rhinestone-encrusted microphone for the energetic performance.  

Meanwhile, the teenager found an unusual way to celebrate Christmas  –  with a crazy socks party.

The get together, which was attended by a few of Selena’s friends, occurred over the weekend.

Selena posted a few pictures of herself and her buddies via Twitter.

‘We’re the 6 best friends that anyone could have’ and ‘Bout to have a crazy socks party…. Pics soon :)’ she wrote as she posed with her pals, shopping in a superstore.

She then posted an image of herself and a female friend donning some cheery Christmas socks, with the Disney star writing: ‘Yes… It happened.’

The goofy outing was certainly a different scene to her holiday in Los Cabos with Justin.

The couple were there for the wedding of one of Selena’s close friends and also to celebrate their one year anniversary.

During their down time the teenagers were spotted looking completely loved up as they lounged poolside as well as beachside in the sunny Mexican setting.

At one point the amorous pair were seen sharing a lingering kiss on the golden sands, before cooling off in the ocean and making a splash on a pair of jet skis.

Putting the drama of recent weeks behind them – which has seen Justin accused of fathering a lovechild – the happy couple frolicked.

Over the course of a few days, they were also spotted lazily sunbathing on sun loungers as a snap happy Justin took photos of his girlfriend.

The popstar couple, who recently denied their own engagement, were in Mexico to attend a friend’s wedding with Selena as the bridesmaid.

The former Wizards of Waverly Place star was dressed in a halter neck sapphire blue dress which complemented her olive skin tone.
