Breakup to makeup. Following a tumultuous past, the ladies of Danity Kane are reuniting for a tour.

Three of the five original members, Dawn Richard, Aubrey O’Day, and Shannon Bex, will hit the road on “The Universe Is Undefeated Tour” in September. The 16-date trek, which includes shows in New York, Chicago, and Los Angeles, marks the first time in four years that the trio has performed together.

The news follows the group’s breakup in 2014 after a studio altercation. Aubrey and Shannon went on to form Dumblonde while Dawn pursued a solo career.

“We have been through a journey of a lot of ups and downs, but on any journey it requires the people involved to not be willing to let go of each other and that’s what we’re on so, we’re super grateful to be back in each other’s lives,” Aubrey tells E! News. “To have survived the last round and truly come together as sisters and do it for ourselves and also for the fans.”

“The conversations started because I think Aubrey and I wanted to touch base cause we hadn’t in a long time and I think we both had feelings of feeling like we needed to have that conversation,” adds Dawn. “We’re sisters at the end of the day and I think if you go through life you still remember like I really want a relationship with these girls even though you go through things, you really want that comradery and so Aubrey and I had a great conversation.”

The tour will feature a performance from Dumblonde as well as a solo set from Dawn. It will commence with the three of them performing Danity Kane’s biggest hits like “Show Stopper” and “Damaged.”

“We’re actually doing a combination of our solo project which is Dumblonde, we have our second album coming out soon, so we’re doing a combination of our album,” says Aubrey. “Dawn is going to be doing her solo performances from her solo album and then together we’re going to come back together, DK3, and also be performing Danity Kane songs that all the fans love. So you’re getting the best of all of our worlds, solo worlds and group worlds.”

A new album could also be in the works. Dawn, Aubrey, and Shannon released their album DK3 as a trio in October 2014.

“You never know,” Aubrey said when asked about new music. “They’d have to come to the show, but there will be new performances on the show.”
