Even though Dancing With the Stars 2013 is over for the season (after Kellie Pickler and Derek Hough took home the Mirror Ball!), we aren’t done with the cast yet. In fact, everyone got together to celebrate pro Mark Ballas’s birthday late last night.

Even cuter was the fact that they went to the Chmerkovskiy brothers’ house to ring in his big day! And the most adorable part? They all sang to him after presenting him with a cake — and posted the video on Vine!

A little after midnight, Mark tweeted his friend Alex’s video, writing, “Birthday song at the Chmerkovskiy house, thank you @iamValC @MaksimC @AlexSanderNYC  #fam #16years.”

Aww! We can even hear Maks leading the pack as they all sang. Since they are
all in New York City post-DWTS finale, they all partied it up together late Wednesday night, too! Check out the second Vine video of them below — including Derek, Jacoby, and Karina, too — as they party the night away.
