The new year brings new beginnings for Meg Ryan and John Mellencamp.
The pair have spent time together on Martha’s Vineyard and in New York City in recent days, enjoying a fresh romance just as Mellencamp has announced his separation from wife Elaine after 18 years of marriage.
A source close to Ryan, 49, says the actress and the rock star, 59, began dating about seven weeks ago, and that Mellencamp and his wife had been separated for some time before that.
