JLo proved that she still does it best as she gave the crowd her best booty-shaking moves at the charity concert

Jennifer Lopez proved she’s still got the best booty in the business as she surprised audiences by closing the show at We Day in Vancouver.

And it was some surprise.

The star brought the house down as she took to the stage at the Rogers Arena in Vancouver to perform her hits Get It Right and Big Booty on Wednesday night.

Wearing a glittering gold leotard and knee high leather boots, the 45-year-old singer showed off her toned figure as she danced around the stage during the energetic set, leaving her long brunette hair loose around her shoulders.

Starting her performance in a beaded white coat, JLo stripped down to the raunchy one piece mid-set as she showed the crowd how it’s done.

Let’s face it, JLo was twerking long before Miley and Minaj were on the scene.

Hosted by Disney pop princess Selena Gomez, over 20,000 people came to watch the event, organised by Free The Children to celebrate the power of young people to change the world.

Selena also appeared at the event last year, and as a young artist herself, the cause is close to her heart.

“When people look at me, they don’t see a 22-year-old figuring it out as she goes. They see what they want to see,” she told the crowd.

“I know what it’s like to be judged and to be put down. I know what it’s like to have other people have opinions of you without knowing you.”

“I want to say you are not defined by an Instagram photo, by a like, by a comment. That does not define you. I want you guys to know that the trick is to focus on the love.”

Wise words there, Sel.
