Let the wedding bells ring out because Kym Johnson and Robert Herjavec are getting married on July 31. Although the duo kept the exact date of their planned nuptials a secret from the press, their Dancing With The Stars season 20 co-star Noah Galloway spilled the beans with a July 30 tweet.

The tweet, which was posted at 10:30 AM Pacific time Saturday morning, read "Headed to LA today for @robertherjavec and @kym_johnson wedding tomorrow. Couldn't be happier for the both of them." The Shark Tank star responded to Galloway's tweet with a cheerful note of his own that read "get ready to do some dancing Noah ! Don't worry, I will show you how !"

Kim Johnson and Robert Herjavec's romance

Professional dancer Johnson, 39, first met the 53-year old Herjavec when they were paired up for the spring 2015 season of DWTS.

Although they didn't win the glittering Mirrorball Trophy --that honor went to actress and model Rumer Willis and Valentin Chmerkovskiy-- their obvious chemistry made them favorites with show fans. They took their time formally confirming the romance, but spent plenty of time together.

After less than a year of dating, Herjavec popped the question to Johnson in February. Since then, they've shared wedding planning details via a series of exclusive People reports. Said exclusives have seen Johnson engaged in several wedding-centric activities, including trying on wedding dresses with pal and former Dancing with the Stars contestant Carson Kressley along to offer up opinions and sampling champagne for her reception.

Bachelorette party tip-off?

Earlier in the week, Johnson Instagrammed photos from her bridal shower. The group included a number of DWTS alums, including Johnson, Burke, Edyta Sliwinska, and Anna Trebunskaya.

While Johnson partied it up with friends, Herjavec hit the Pelican Hill Golf Club to enjoy a quiet celebration of his own.
