"Why is he so cute tho," Rose captioned a video of the smooch on Instagram.
The Amber Rose Show host and Chmerkovskiy were first linked in October after meeting on Dancing with the Stars Season 23. The couple appeared to confirm their relationship Jan. 4 by sharing another kiss in an Instagram photo.
"It's amazing!" Rose gushed on her Loveline podcast the same day. "It's so good. It's been four months now and it's awesome. I love his family and everyone's so great and he's great."
"Right now it's just absolutely amazing and I'm super, super happy," she added. "I didn't want to put it out there [initially] because I wasn't sure about us yet."
Rose was previously married to Wiz Khalifa and shares 3-year-old son Sebastian with the rapper. She was partnered on Dancing with the Stars with Chmerkovskiy's brother, Maksim Chmerkovskiy, who welcomed his first child with Peta Murgatroyd this month.
