Beyonce [ tickets ] will bring her globe-trotting "I Am..." tour to the US this summer, topping it off with a four-night engagement in Las Vegas.

The six-week outing kicks off June 21 in New York City, rolling through July before the pop diva puts the finishing touches on the trek with the four-night Vegas residency, which launches July 30 at the new Encore Theater at the Wynn Las Vegas resort. Dates are below.

Tickets for the tour go on sale to the general public April 25, with seats being made available to members of Beyonce's fan club in a pre-sale event beginning April 20. More information on the pre-sale can be found at Beyonce's website.

Beyonce, currently on tour in Europe, will perform songs from her latest album, "I Am ... Sasha Fierce," as well as material from throughout her career, according to her website, in a high-tech production that includes the singer's all-female band.

The new album surfaced in November, quickly becoming Beyonce's third consecutive studio album to top The Billboard 200. The set, which has racked up worldwide sales of more than 3.5 million copies, according to her record label, is separated into two discs to reveal different sides of the superstar's personality: "I Am ..." showcases a group of intimate ballads, while "Sasha Fierce" represents Beyonce's sensual, aggressive, fun, glamorous, dance-oriented side.

"Sasha Fierce is my alter ego and now she has a last name," Beyonce explained in her bio. "I have someone else that takes over when it's time for me to work and when I'm on stage--this alter ego that I've created that kind of protects me and who I really am."

The album has spawned two chart-topping singles, "Single Ladies" and "Diva," along with a number of other radio-friendly tunes, including "Ego," which is included on the deluxe edition of "Sasha Fierce" and is slated to become the album's third official single.

The deluxe edition of the album, which contains five bonus tracks, counting "Ego," was released simultaneously with the standard version last fall.

"I Am ... Sasha Fierce" follows 2006's mega-smash "B'Day," which won a Grammy for Best Contemporary R&B Album and has achieved triple-platinum status.
