Surprise! Emily Ratajkowski shocks Instagram with sudden city hall marriage

Mazel tov to Emily Ratajkowski -- a very unexpected mazel tov!

The model shocked Instagram Friday when she announced she just tied the knot! Emrata wed Sebastian Bear-McClard, her boyfriend of just a few weeks, at a Manhattan courthouse.

The bride wore a mustard-colored jumpsuit and black hat. "Sooo," she captioned two teasing photos, "I have a surprise."

In one photo, she's flanked by two friends who served as witnesses to the wedding. In another, she's cuddling a dog. And then...

"I got married today," she captioned a selfie of her new husband kissing her on the cheek.

It's unclear how long the two have been together, but reports surfaced in January that Ratajkowski was no longer living with her longtime boyfriend, music producer Jeff Magid.
