Heidi Klum isn't one to talk about her private life, yet she's declaring her love for her boyfriend on social media. The leggy supermodel shared a rare snap of her and her much younger boy toy Vito Schnabel on her Instagram account on Monday along with a sweet birthday message.

And while Klum hasn't said much about their relationship, it does appear that she is making some big changes in her life. The German-born supermodel is apparently eyeing her own private island in Connecticut. Klum will have to pay a whopping $11 million if she wants to call it home.

According to the New York Post back in June, Klum is looking to purchase Tavern Island off the coast of Connecticut, which boasts three-and-a-half acres and a spectacular view of the New York City skyline. The island includes a six-bedroom home built in 1900 and comes with a guesthouse, boat house, pool and a private beach.

Klum regularly splits her time in California, New York City, and her native Germany. Her four children though go to school regularly near Los Angeles.
