Christie Brinkley’s son Jack Brinkley-Cook frolics on beach with tennis star Genie Bouchard

Christie Brinkley’s musclebound son Jack Brinkley-Cook was seen frolicking on the beach in Miami with tennis star Genie Bouchard on Saturday.

In a sighting sure to set rumors flying, the bikini-clad blonde was seen leaning on Jack’s shoulder and clinging to him as they soaked up the son on a deck chair.

Jack, 27, went shirtless on the beach, showing off his sculpted physique as he strutted his stuff across the sand with Genie.

Genie, an accomplished tennis player who has played at Wimbledon, the Australian Open and the French Open, glowed during her latest outing.

She showcased her lithe, athletic figure in a throwback chic gingham bikini as she pranced about across the sand.

The 28-year-old, who was born in Montreal but has moved to Las Vegas, could be spotted laughing uproariously while sharing a chat with Jack.

Genie, who with her twin sister Beatrice was named after Prince Andrew and Fergie’s daughters, used to date NFL heartthrob Mason Rudolph.

Mason, the quarterback of the Pittsburgh Steelers, was with Genie for about two years before TMZ Sports reported their breakup this May.

Meanwhile, last year Jack broke up with his girlfriend of over four years, Nina Agdal, a model who shot to global fame for dating Leonardo DiCaprio.

Nina, who is 17 years younger than Leonardo and three years older than Jack, broke up with Leo in 2017 back when she was 25 years old.  

Christie shot to fame covering the Sports Illustrated Swimsuit Issue in the 1970s, and Nina has since in her footsteps to cover the magazine.

Jack’s biological father is Christie’s third husband Richard Taubman, but he was adopted by her fourth husband Peter Cook, who is not to be confused with the English comedian of the same name. 

Peter went on to marry a woman called Suzanne Shaw, who sniped in 2012 that she had jetted off to Indonesia because of how ‘vengeful’ his previous wife Christie was.

Suzanne wrote to the New York Post: ‘The black cloud of Christie Brinkley’s hate [that] has hung over our lives for the five years I have been with Peter, and has taken an unhappy toll on me and my daughter’s life — on all our lives. I needed a break.’

Jack sprang to Christie’s defense, calling the claims ‘lies’ and telling the MailOnline: ‘I rarely ever hear my mother or father discuss one another mean while there have been many instances where I have heard my father’s wife mention my mother.’

In 2014, Suzanne left her husband, told Page Six that ‘I fell under Peter’s spell’ and publicly apologized ‘for my part in causing Christie any unnecessary pain.’
