Kym Johnson and Robert Herjavec are celebrating a lot more than just the holidays right now. The Season 20 Dancing with the Stars couple are expecting their first child together! Kym, 41, announced her big pregnancy news on Monday by sharing a funny picture of a sonogram showing what appears to be a big hand. "'It's a thumbs up,'" the pro dancer captioned the image on Instagram, which Robert then reposted on his own account. And on Tuesday, Kym posted a picture of her little white dog standing behind the book Good Dog, Happy Baby: Preparing Your Dog for the Arrival of Your Child. "Shouldn't it be the other way around?! Happy Dog, Good Baby... I have a feeling we're really going to need this!" Kym wrote. Kym and Robert met and seemingly fell in love on Dancing with the Stars in Spring 2015 when they competed as a professional and celebrity pairing. (They placed sixth that season). The couple got engaged in March 2016 and then quickly tied the knot in Los Angeles in late July of that year. After appearing on Dancing with the Stars together, Kym told People that her relationship with Robert was amazing. "I didn't think it was possible, but it just kept getting better," Kym said of her romance. "I'm just so happy to be going through life with Robert. He's the most incredible person." "I enjoy every minute I spend with Kym," Robert added. "When I met her I felt complete." Following a three-season hiatus, Kym returned to Dancing with the Stars as a pro partner for Season 24 when she was partnered with Mr. T, but she decided to skip Season 25.
