R&B mega star Alicia Keys and "American Idol" winner Jordin Sparks will join forces on a three-month, national tour launching in April.

According to Billboard the two singers will be hitting the road beginning on April 19th in Hampton, Virgina and will see stops in Philadelphia, Chicago, Los Angeles, New Orleans, Miami, and Atlanta before ending in New York City's famed MadisonSquareGarden on June 18th.

As previously reported, Keys recently won a Grammy award for Best Female R&B Vocal Performance, for "No One." The song was the first single off of Keys' third solo album, As I Am, which is quickly approaching triple platinum status. Both "No One," and Keys' second single, "Like You'll Never See Me Again" hit No. 1 on the charts.

Sparks saw time in the top 10 as well, with her debut single "Tattoo" hitting No. 8 on the charts. Her second single "No Air" featuring Chris Brown is also climbing Billboard's Hot 100. A video for that track directed by Chris Robinson ("Roc Boys," "You Don't Know My Name") is expected to debut later this month.
