If you can believe it, Christie Brinkley, Oprah Winfrey, and Howard Stern are all marking a birthday milestone this year: They're turning the big 6-0!

Christie, who is celebrating her special day Feb. 2, told "The Insider" at the 50th anniversary of the Sports Illustrated Swimsuit Issue what she plans on doing.

"Whenever I celebrate, it's really all about gathering family and friends around," she said. "I like things low-key and barefoot."

But spending time with family isn't the only thing the supermodel is doing to celebrate her birthday. She's also on the cover of this week's People magazine clad in a bright blue bathing suit and showing how her body is just as great at 60 as it was when she appeared in the magazines swimsuit issues in the 1970’s.

Kevin Frazier, co-anchor of "The Insider," caught up with Oprah at the Screen Actors Guild Awards this year, and she revealed her plans for her big day, Jan. 29. "I intend to have a wonderful time with myself, Stedman, and my dogs," she said. "It's going to be great."

The former "Oprah" host reportedly had been planning a big party but canceled the shindig at the last moment because the guest list was getting out of hand.

"America's Got Talent" judge Howard Stern turned 60 on Jan. 12, and "The Insider" got the scoop about the famous folks who will be attending his big bash on January 31 from his wife, Beth, while she was promoting the Kitten Bowl at Time Warner Cable Studios, airing on the Hallmark Channel Feb. 2.
