Heidi Klum isn't one to open about her personal life, so it was quite surprising to see her share a photo of her boyfriend Vito Schnabel on her Instagram account on Saturday.

In the photo, Klum is wearing her much-talked about butterfly costume that she donned for Halloween while Schnabel is in full costume as well, as legendary actor Marlon Brando.

Klum captioned the photo with, "Have the best time with you V."

Meanwhile, there have been rumors that Klum might have tied the knot for the third time.

Rumor has it that the German beauty married her boyfriend Vito Schnabel as she was recently spotted wearing a gold band on that all-important finger, according to Rumor Fix last Friday.

The couple, who have been dating since earlier this year, were spotted taking a romantic stroll together in Paris, where Klum apparently flashed a gold band on her wedding finger on her left hand.

There's also speculation that the band might be an engagement ring, although both Klum and Schnabel haven't made any comments about the rumors. Schnabel dated actresses Demi Moore and Liv Tyler along with model Elle Macpherson before hooking up with Klum back in February. Klum herself just finalized her divorce from ex-husband Seal this month, too.
