Selena Gomez has come a long way since her Disney days, but never was it more obvious than when the brunette beauty celebrated her 23rd birthday in London.

The Wizards Of Waverly Place actress made the mature decision to mark the occasion with an intimate group of girlfriends in a hot London night spot, Beach Blanket Babylon on Thursday.

And Selena – currently on top of the world with her new album and seemingly single status – dressed to kill in seriously-sexy leather from head-to-toe, keen to show off her toned figure.

Ready to rock: Selena Gomez stepped out to mark her 23rd birthday in London in an all-leather outfit

There was no boys allowed at the birthday bash, even though Selena garnered plenty of attention for her spicy outfit.

She wore a tightly-fitting leather crop top that cut just short of her toned tummy as she paired it with wet-look jeans.

And the actress-turned-singer added pointed patent boots for extra effect, choosing to keep her leopard print jacket in one hand as she pounded London’s pavements.

Selena’s transatlantic career is about to take off again, after revealing the title and release date of her new album as Revival on October 9, 2015.

She even teased a first release from the record because opening track Good For You played in the back of a cryptic Instagram post.
