Rose, who met Chmerkovskiy while competing on the latest season of Dancing with the Stars, posted an Instagram photo on Wednesday of the couple kissing on the lips.
Rose captioned the sweet image, "My Love" with a heart, and later that night, Chmerkovskiy posted a photo of himself kissing Rose's hand as she intimately leaned her head on his shoulder. Chmerkovskiy captioned the picture he shared with a simple rose emoji.
On her Loveline podcast yesterday, Rose publicly declared her strong feelings for the 30-year-old pro dancer. Although she didn't name Chmerkovskiy directly, she referred to being in love with her new "bae," whom she recently spent time with in New York City.
"It's amazing, it's so good, it's so good," Rose said of her new relationship on the podcast. "It's been four months now and it's awesome. I love his family and everyone is just so great and he's great."
However, the 33-year-old curvy model admitted it's "so hard" to date someone in the spotlight.
"It's like, you date someone so you have to be with them for years and forever and you have to get married," Rose explained. "You date people to get to know them and you either like them after six months or you don't, and you just figure it out along the way. Right now it's absolutely amazing and I'm super, super happy."
After meeting on Dancing with the Stars in Fall 2016, dating rumors began circulating when Chmerkovskiy and Rose took flirty photos together at her late October birthday party and then they celebrated Halloween together.
The couple became increasingly more open about their romance as time went on.
On December 9, they were spotted holding hands on a dinner date in Los Angeles, and then one week later, Rose posted a sexy portrait of Chmerkovskiy on social media and captioned it, "When you said you were going to stay off social media until the New Year but Bae keeps posting hot ass pictures."
Rose and Chmerkovskiy were initially "just friends," a source previously told Us Weekly, but it "turned into more" and they began "hooking up."
