It would seem that Justin Bieber's ex has well and truly deserted her former Disney star persona and has morphed into one seriously hot young lady.

Stepping out in this glittering creation, Selena showed off her impressive figure and killer pins.

Been working out much, Ms Gomez?

And not only was Selena looking gorgeous on the red carpet, the star also performed at the awards which were being held at Culver City, California.

Multi talented lady, eh?

The Spring Breakers star performed her track 'Come and Get It' and has already received some great reviews.

Ahead of the performance, she wrote: "MTV Movie Awards tonight I am so excited and nervous for the performance tonight. #comeandgetit #movieawards,"

In other Gomez news, the star is still single since splitting with Justin Bieber back in January.

We bet these pictures didn't do much for poor old Biebs' heartache.
