So in love!
"I am so proud of you... I love you and everything that you are @MaksimC," the 29-year-old dancer captioned the sweet snapshot of herself kissing her hubby-to-be.
Maks, 36, and Peta — who are rumored to be expecting their first child together — first became an item in 2012 and dated for 10 months before calling it quits. They rekindled their romance last year and Maksim proposed to Peta in December 2015.
