Tim McGaw's 'Superstar Summer Night' is shaping up to be one star-studded event, thanks to a continually evolving lineup. New additions to the already all-star lineup include Keith Urban, Dierks Bentley and Lady Antebellum. But it's not just country acts that are going to rock out with McGraw. Pitbull, the Cuban pop star known for his addictive Latin dance jams and 'hip-pop' tracks, is also newly slated to perform.

We love it when pop acts come over to the country side of things. R&B singer Ne-Yo, with whom McGraw has collaborated, is also set to perform. Other country acts confirmed for the event include Taylor Swift, Luke Bryan and Jason Aldean.

The talent at this event is not merely A-list. It's A-Plus!

The event tapes on Monday, April 8 at the MGM Grand Garden Arena in Las Vegas. It will be broadcast at a later date on CBS, much like previous specials surrounding Lionel Richie and the women of country music. The two-hour event will benefit ACM Lifting Lives, which is the philanthropic arm of the Academy of Country Music.
