To celebrate her partnership with T-Mobile, Shakira performed a free concert in New York City's Bryant Park on Wednesday.

The 36-year-old performed many of her hits, including Waka Waka, Loca, Underneath Your Clothes and Whenever, Wherever. She showed off her impressive dance moves and was also joined on stage by Wyclef Jean for their 2006 collaboration Hips Don't Lie.

Shakira and T-Mobile's union will benefit both parties in terms of promotion.

"Shakira is an extraordinary, global entertainer who certainly understands the importance of being connected while she travels the world," said Mike Sievert, the chief marketing officer of T-Mobile, in a statement. "She has a passion for communicating with her fans across many platforms and we knew that we could create a collaborative partnership to reach her fans and our customers in unique and exciting ways."

Despite giving birth to her firstborn Milan less than a year ago, Shakira was in perfect shape on stage. The 36-year-old spent a month at home in Barcelona to shed the baby weight. But, she was also careful during her pregnancy.

"I did Zumba throughout my pregnancy," Shakira recently told Self magazine. "That helped me not gain too much weight."

Shakira also told the magazine that she doesn't spend too much time worrying about her imperfections.

"I don't obsess over my flaws, because I see my body as a whole," she said. "Besides, I think men appreciate confidence more than perfection."
