Mary J. Blige mistakenly included on "Lovers & Friends" festival line-up...

Oop! Mary J. Blige isn't going to be held accountable for false advertising on a flyer. Fans were really excited to see the “Family Affair” singer’s name on Las Vegas’ Lovers & Friends festival line-up this week. However, the R&B star took to Instagram to share some sad news: her name was listed in error. The festival is scheduled to take place at the Las Vegas Festival Grounds on May 4th.
