Peta Murgatroyd couldn't be more in love with her fiance, fellow Dancing With the Stars alum Maksim Chmerkovskiy.

On Tuesday, Peta -- who's currently pregnant with the couple's first child -- shared a pic of the two lying in bed with another, with a shirtless Maksim tenderly placing his hand on her. The 30-year-old dancer called Maks her "best friend" while sweetly wishing him a happy anniversary. Maksim proposed to Peta last Dec. 5 onstage at his Sway: A Dance Trilogy show in Miami, Florida.

"To my best friend, with whom I get to spend the rest of my life with.....You are everything that I've always dreamed of and I can't wait for the next 50 years where I can fall asleep beside you, and fall in love all over again #happyanniversary #inlove #soontobethree," she wrote.

ET spoke with Maks in October, when the excited father-to-be said that the upcoming arrival of his baby boy definitely made his decision about not returning to DWTS season 24 easy.

"There's no way!" Maks, 36, said. "He's going to be a month and half old [when the new season starts] and I'm gonna say, 'OK, I'll see you in 3 months buddy?' No, that's not gonna happen."
