Brinkley was recently photographed wearing a black, two-piece ensemble at her home in Long Island, N.Y., and the images helped her become a trending topic on Yahoo! Sunday and Monday.
The ex-wife of rock 'n' roll icon Billy Joel said she doesn't starve herself to maintain her figure, however.
"Believe me, I love a good chocolate chip ice cream," she once told Shape magazine. "I'm not going to go for some lousy version of it. If I'm going to have it I'm going to have a really good one."
Brinkley also made headlines recently when she played disc jockey at the South Fork Natural History Museum's fundraising party, SoFo Rocks, which raises money to preserve the natural environment of Long Island's South Fork region, The Inquistr said.
She was widely quoted, as well, for weighing in on a photo-shopping controversy involving an ad for "The Heat," a new movie starring over-40 actresses Melissa McCarthy and Sandra Bullock.
"I've been photoshopped before. I think it's kind of weird to do that with actors because, obviously, you can't photoshop a movie and you're going to be seeing the actors as they are in the movie; you get to know actors and you just love them the way they are... We all love Melissa McCarthy just the way she is," Brinkley told TV's "Entertainment Tonight."
"Everything gives the message [that] it's not OK to be old. It's not OK to be fat. It's not OK to have any imperfections and there's too many outlets that are ready to pounce and it's unfortunate that that's what seems to sell magazines," Brinkley said. "I wish that there was some way we could change that."
