'Dancing With the Stars' Julianne and Derek Hough Join Season 20: Find Out Which Celebrity They're Related To!

They should probably just change the name of Dancing with the Stars to Dancing with the Houghs -- after all, there are about to be three of them on the 10th anniversary season. Now you might be scratching your head and trying to do the math: Julianne makes one, Derek makes two, so who's the third? Well, it turns out that one of the stars is actually related to the two professional dancers. That's right: R5 singer Riker Lynch, who will be teaming up with Allison Holker, is actually Julianne and Derek's cousin.

And you better believer that the musician has that "Hough blood inside him!" So will he be able to take home the mirror ball trophy this year?

Riker and Allison sat down with E! News to talk about the new season of the show and about the bizarre family connection.

When asked if he ever gets the chance to see his cousins, he said he tries to as much as possible but with all their commitments it can sometimes get difficult.

"Our schedules are very, very busy, but when we do see each other, it's always good to catch up," the singer told the site, adding that Derek was "super pumped" when Lynch told him he was going to be a part of Season 20.

So is Riker excited that his cuz is going to be back to shimmy and shake, following the announcement that he was taking some time off?

Well, sort of.

"I was like, 'I'm going to be able to steal all of his moves 'cause he's not on the show,' and then they announced him right at the end [on Good Morning America] and I was like, 'Oh crap!'"

The new season of DWTS will kick off March 16 at 8 p.m. on ABC.
