Are Christie Brinkley and John Mellencamp dating?

Photos of the 61-year-old supermodel all smiles with the 63-year-old musician at The Bowery Hotel in New York City on Monday night may prove just that.

The couple was having dinner inside the hotel, with Brinkley looking stunning while dressed down in high-top sneakers, a pale yellow jacket, blue scarf and cuffed jeans. Mellencamp, on the other hand, sported a short-sleeved coat and denim jeans, the Daily Mail UK reported.

Eyewitnesses say that Mellencamp was the first to arrive at the hotel and was joined by Brinkley later on. The two spent an hour together inside and then left the hotel in his car.

Whether or not the two are indeed a couple, a source close to them revealed, "It's not like that. This is the first time they've ever been out together," according to Entertainment Tonight Online.

Brinkley's last reported public relationship was with her ex-husband Peter Cook. They went their separate ways back in 2008 and have two children, Jack, 20, and Sailor, 17. The supermodel also has another daughter, Alexa Ray, 29, her child with singer Billy Joel.

Mellencamp had previously dated actress Meg Ryan for three years before they parted in August 2014, but have remained close friends, according to People.
