Christie Brinkley
is in an Empire State of Mind!

The 61-year-old took to New York’s Empire State Building on Tuesday to celebrate the launch of Smile Train’s “Give a Smile, Get a Smile.” And the model was, in fact, all smiles as she sported a super-short, cream-colored dress that showed off her amazing legs.

Photos of the event show Brinkley beaming as she posed with a donation jar, wearing a black oversize coat, over-the-knee boots and a conductor-style hat. She later ditched the coat and hat and posed for pictures both solo and with Smile Train founder Charles Wang.

She even took a few snaps in front of a small replica of the Empire State Building.

The model has a lot to smile about these days, as she recently went public with her relationship with
John Mellencamp
(not to mention her envy-inducing tropical family vacation over Thanksgiving).

In an interview on Howard Stern’s SiriusXM radio show last month, Brinkley shut down questions about marrying 64-year-old Mellencamp.

“I am leery of discussing my relationship, because I don’t want to jinx it,” she said.

Although tight-lipped about possible nuptials, Brinkley said one thing is for sure: “[Mellencamp] has to stop smoking.”

“He won’t do it. He thinks it makes his voice sound better,” she said on the radio show. “The voice is already made. He has to stop.”
