It looks like supermodel Heidi Klum is taking her romance with art dealer Vito Schnabel public… at least on social media.

The 41-year-old posted a pic on Instagram with 28-year-old Schnabel, son of director Julian Schnabel, while on vacation, marking their debut as a couple.

Klum also posted a pic of Schnabel diving off a yacht, writing, “Happy birthday, V.”

Klum and Schnabel have been an item for about six months. They were first spotted kissing at an Oscars party at the beginning of March.
