Ballas and Jean make up the musical duo Alexander Jean, whose song "Roses and Violets" was prominently featured in the latest season of Dancing With the Stars.

With Ballas' engagement, we now have multiple pros getting engaged and married over the past few months. Pros Maks Chmerkovskiy and Peta Murgatroyd recently got engaged, and Witney Carson just got married! Plus, Julianne Hough is engaged to be married to NHL player Brooks Laich.

Will this put pressure on some of the single DWTS pros, like Derek Hough? That remains to be seen, though sister Julianne alluded to Derek's work being his greatest passion in life.

It is also unknown as to who will be returning for the upcoming 22nd season of Dancing With the Stars. The celebrity cast and returning pros are generally announced in the weeks leading up to the next DWTS premiere.

Dancing With the Stars returns for a new season on Monday, March 21 at 8 p.m. ET/PT on ABC.
