Christie Brinkley — Still Got It & Staying Single

Christie Brinkley looked glamorous as the supermodel hosted the St Barth Hamptons Social Life magazine cover party in the Hamptons — but her boyfriend John Mellencamp has to accept that she's staying glamorously single! The rocker's dream of marrying health-nut Christie has gone up in smoke!

Christie, 62, worries that heavy smoker John — who’s already suffered one heart attack — could drop dead of another killer cardiac attack at any moment, sources told The National ENQUIRER. “After a year together, Christie’s still crazy about John. But she worries about his health and she doesn’t want to be a widow,” snitched an insider.

As The ENQUIRER reported in December, 64-year-old John was lobbying hard to marry the famous supermodel. She was even his first big romance since breaking up with longtime love Meg Ryan. But four-time divorcee Christie was dragging her feet. “John thinks dating should lead to a wedding, but he’s having trouble convincing Christie,” spilled a source.

Months later, the model has remained dead-set against saying “I do” to three-time divorcee John — mainly because she’s terrified the “Little Pink Houses” rocker’s heart will give out, sources said. John had a heart attack in 1994 due to smoking four packs a day. When discussing how docs warned him to stop smoking, John said, “I’ve just accepted that cigarettes will probably kill me — and that’s that!”

In 2015, John puffed his way through an appearance with David Letterman on "The Late Show." In contrast, “Christie is a health freak who works out and eats right,” said a source.

The bouncy blond said in an interview: “I’ve talked to John about this: he has to stop smoking. He won’t do it. He thinks it makes his voice sound better.”

For now — after months of an on-again/off-again romance — a source told The ENQUIRER: “Christie is happy with the arrangement she and John have," adding: “They live separate lives, but still come together several times a month.”
