Rumer Willis may have been the one receiving all of the congratulations when she took home the mirror ball trophy on Dancing With the Stars in June, but now, she's the one sending out well wishes.

The DWTS season 20 champion took to Instagram on Saturday to congratulate her "wifey," Peta Murgatroyd, on her engagement to fellow pro dancer Maksim Chmerkovskiy on Saturday.

"My wifey is getting married!!! ?love you @petamurgatroyd, so happy for you," Willis, 27, wrote.

The House Bunny
star shared another pic on Sunday, posing with Nicole Volynets and Murgatroyd, who is clearly showing off her stunning ring in the snap.

Willis wasn't the only one to congratulate the couple over social media, as many DWTS pros and former contestants shared their excitement following Chmerkovskiy's onstage proposal at the Sway: A Dance Trilogy dance show in Miami, Florida.

Tom Bergeron, host of the dancing competition show, kept his message straight forward, simply re-tweeting Chmerkovskiy's announcement with, "Congratulations!!"

Tony Dovolani was stoked about having Chmerkovskiy join the marriage "club."

But Val Chmerkovskiy's post was by far the sweetest of them all.

Chmerkovskiy, 35, and Murgatroyd, 29, have been dating on and off since 2012. Watch the video below to hear more news on the lovebirds' engagement.
