After months of playing coy, the model finally went public with her relationship with "DWTS" pro Val Chmerkovskiy.
Rose, whose birth name is Amber Levonchuck, shared a photo of the two kissing, with the caption "My love."
For his part, Chmerkovskiy shared a photo of him looking cozy with Rose. He captioned the photo with just a rose emoji.
Rose, 33, and Val Chmerkovskiy, 30, met while competing during the ABC dance competition's 23rd season. Rose was partnered with brother, Maks Chmerkovskiy.
It seems that Maks Chmerkovskiy approves of their relationship. Rose was present at the baby shower for his fiancée, Peta Murgatroyd.
The two dancers welcomed their first child, Shai Aleksander Chmerkovskiy, Wednesday morning.
Rose shared a snap from the shower with the caption "My brother for life @MaksimC #babychmerkovskiy."
Maks Chmerkovskiy told "GMA" in October that viewers saw a different side of Rose on the dance floor and off.
"One of the beautiful things about this show is you get to find out who the person really is behind the lights and stuff," he said. "I was surprised to find out she is just so chill and down to earth. I was expecting some sort of internet-vixen type of personality, and it was far from the truth."
Val Chmerkovskiy went on to win Season 23 of "Dancing With the Stars" with Olympic gymnast Laurie Hernandez.
