Nick will be competing on Season 21 of "Dancing With The Stars" -- which premieres Monday night (Sept. 14) at 8 p.m. ET on ABC -- following in little bro Aaron's footsteps, who tore up the dance floor with Karina Smirnoff back in 2009.
An "awww"-worthy Twitter exchange between the two showed how they have each other's backs. Hopefully, this is another chance for the Carter name to slay the competition all the way to first place.
In 2009, Aaron joked to MTV News that he didn't have Nick's vote because Nick loved fellow contestant, football player Michael Irving. But it seems like Nick and partner Sharna Burgess, who will be going by #TeamSharNick, totally have Aaron's vote this season.
Let's look back on some sweet moments between the blonde bros:
