Beyonce adds fourth A.C. concert

ATLANTIC CITY, N.J., May 8 (UPI) -- Pop star Beyonce has added a fourth show to her concert series at the new Revel resort in Atlantic City, N.J., the venue announced.

The shows are to take place May 25-28. The dates mark the 16-time Grammy Award-winner's first live concerts since last summer. She gave birth to daughter Blue Ivy, her first child with her husband, rapper Jay-Z, in January.

The first three Revel dates sold out in less than a minute after tickets went on sale to the general public, said the resort, which officially opens Memorial Day weekend.
