The worlds of two reality singing competitions are colliding!

Gwen Stefani Is Heading Back To 'The Voice' For Season 9!

The X Factor USA didn't last long, but it did allow for some magical acts to come together, including its third and final season's girl group Sweet Suspense that was put together in the same manner as the previous season's Fifth Harmony.

Sweet Suspense consisted of Summer Reign, Celine Polenghi and Millie Thrasher. They have steadily been on the rise, but within the last month or so Polenghi decided to quit.

Reign and Thrasher were seen at events without her and the buzz followed along with Polenghi tweeting a little cryptically.

On May 17 she told her Twitter followers, "luv u guys no matter what" and then on June 3 she added to her cryptic messages by essentially saying she was no longer happy and needed to reclaim her happiness by leaving the group.

Reign and Thrasher are still going on as Sweet Suspense and revealed on June 3 big "exciting news" was on its way.

Part of the big news is that they'll be hitting the road this summer for the PopNation Tour, which they dished Wednesday.

How does The Voice tie into this? Well that's the other news. The Voice Season 7 contestant, Bryana Salaz, who was on Gwen Stefani's team, has been named Polenghi's replacement so Sweet Suspense is still a three-piece act. Reign and Thrasher revealed Thursday that they "can't wait" to debut with Salaz.
