Mary J. Blige Back On Lovers & Friends Fest!!! Bumped Up On Lineup 👀

Mary J. Blige shocked Lovers and Friends festival fans just by announcing yesterday she would NOT be performing, and her name was put on the flyer by accident -- but lo and behold, she's back!

On Friday, MJB was re-added to the lineup, and it appears the "error" was really about where she'd been placed on the promotional flyer -- because she's been bumped up several slots to reflect her headliner status ... and she's now happily posting about the event.

Shortly after the changes, Mary posted a smirking emoji and money bag on her IG -- so, basically, she's chuckling all the way to the bank.

Lovers and Friends had originally squashed MJB's name in between the likes of Snoop Dogg, Alicia Keys, Ashanti and several other recognizable music legends.

The updated artwork moves her billing up to the top of the third column, now dwarfing Gwen Stefani, Nelly Furtado, Ciara and more.

Essentially, on the day Lovers and Friends tickets went on sale, the event's promoter had to bow to the Queen of Hip Hop Soul.

Soooo .... let's get crunk, 'cause Mary's back!!!

MJB had also claimed her annual Strength of a Woman Summit conflicted with her scheduled performance ... but fans weren't really buying she couldn't do both as they're happening a week apart!!!
