R&B singer-songwriter Trey Songz, who has collaborated with hip-hop artists Jay-Z, Drake and others, has been added to this year's Essence Festival lineup.

The festival is scheduled for the Fourth of July weekend in New Orleans.

On Wednesday, organizers also announced that Solange is joining the lineup that already includes her big sister, Beyonce.

Beyonce is headlining one of three night concerts during the festival, which runs July 4-7. It'll be Beyonce's second performance in the Superdome this year. She entertained a huge television audience during the Super Bowl halftime show earlier this month.

Other acts scheduled to perform are Jill Scott, Maxwell, New Edition, Charlie Wilson, Keyshia Cole, LL Cool J, Brandy and others.
