(Cover) - EN Showbiz - Beyonc Knowles is preparing to perform four sell-out shows over the Memorial Day weekend.

The star only gave birth to her daughter Blue Ivy in January, but is poised to throw herself back into work commitments. She has been busy rehearsing for the shows in Atlantic City, which will be her first since she performed at the Roseland Ballroom in New York City in August last year.

Beyonc was originally planning to perform twice in Ovation Hall at the Revel Entertainment Complex, but due to demand she added an additional two shows.

Every ticket has been sold for the 5,500 seat venue and the 30-year-old will take to the stage each night from Friday to Monday.

Tickets went on sale for $95 to $495, but some diehard fans are so eager to watch Beyonc perform live for the first time since becoming a mother that they have been shelling out up to $1,700 on ticket selling websites, reports New York Daily News.

Beyonc has also been busy working on her follow-up to hit album 4 and is rumoured to be starring in the new movie One Hit Wonders directed by Glee creator Ryan Murphy. (C) Cover Media
