Janice Dickinson, the world's first supermodel, frolicked on a beach in Malibu on Sunday and showed off her bikini body at 60 years old, the Daily Mail reported. Her outing came amid rumors that she's signed a deal to appear on the upcoming season of the British reality show "Celebrity Big Brother."

Dickinson sported a black halter bikini top with matching bottoms as she enjoyed the sun and waves and strutted her stuff barefoot on the sand. It seemed like a solo beach trip as her fiancé, Dr. Robert Gerner, was nowhere to be seen. She has been engaged to Gerner, 69, for three years, according to the Daily Mail.

She was also spotted during a Starbucks run earlier this month, the Irish Mirror reported, just after rumors started swirling that Dickinson would make a return to reality TV on "Celebrity Big Brother." The upcoming season of the show will feature a U.K. versus U.S. theme.

The former supermodel reportedly signed a £300,000 ($332,340) deal to appear on the show, according to the Sun. Dan Osborne, Danniella Westbrook, former WWE pro wrestler Hulk Hogan and comedian Kathy Griffin are all rumored to be a part of the show as well.

This isn't Dickinson's first foray into reality TV. She's appeared as a judge on "America's Next Top Model" and a contestant on "I'm a Celebrity, Get Me Out Of Here!," according to IMDB. She's also appeared on "Celebrity Rehab with Dr. Drew" and her own series, "The Janice Dickinson Modeling Agency."
