On Friday, as RadarOnline.com's photos show, Sailor Brinkley Cook, 20, and now a model herself, enjoyed a sunset dip in her tiny black bikini on Friday.
Sailor is the child that Brinkley had with Cook, who cheated on the supermodel with his teenage assistant, just 18 at the time.
Brinkley dumped Cook in 2006 and they went through a bitter divorce.
Sailor has said she wound up in counseling because of her dad's misdeeds.
"My parents had just gotten divorced and I was so confused about everything," Sailor wrote on an Instagram post where she was wishing her best friend a happy birthday earlier this year.
"I remember throwing a temper tantrum during a session one day and i remember a very shy and very small girl i had never seen before (whos parents also put her in banana splits) calming me down and telling me about her parents and how its all gonna be okay. That was the start of a lifetime of friendship."
"There was this little after-school counseling session for kids with divorced parents that the school put me in called "banana splits". Basically all we did was make banana splits and talk about how we have 2 christmas' and how that was a plus lol (sic)."
Now, however, Sailor seems to be carefree as she enjoys her break in Miami during Art Basel.

Sailor's long blonde hair was wet and pushed back, and she appeared to be make-up free during her Miami day.
Her black bikini was as tiny as it could be! She also wore two necklaces and large hoop earrings.
Sailor told The Daily Mail earlier this year, that she's suffered over being compared to her iconic blonde model mother. "'I've never brought it upon myself that I have to be like her… that's not possible. She's had a career for 50 years." And yet, at age 15, Sailor signed with a modeling agency.
Sailor's dad Cook shocked America when it was learned he'd cheated on Brinkley teen mistress Diana Bianchi. It was Brinkley's fourth marriage. Earlier this year, Radar reported on Cook dating Kasey Dexter, the former mistress of Ramona Singer's ex!
"I'm just trying to live my life," Sailor has said after her parents' messy split. "I want people to realize I have my own things going for me."
Sailor has confided she was chubby as a child, but look at her now!
"I've dealt with insecurity and body image issues my entire life," said Sailor, who is now a student at New York's Parsons School of Design. Her proud mom Brinkley has said her daughter is "practical and no muss, no fuss."
