The 8.31-acre property stretches across Jupiter Island, from the Atlantic Ocean to the Intracoastal Waterway.
Multiple luxurious homes on the estate include a combined 10 bedrooms, 12 bathrooms and six half-baths in 31,800 square feet, according to the former listing. Amenities in the main house include a pair of 1,900-bottle wine cellars, a bar, a movie theater and an elevator.
The property includes 172 feet of ocean frontage and 370 feet of Intracoastal water frontage. There are also two pools, a spa, tennis court and a boathouse.
The buyer is the family of Lex Wexner, founder of Victoria’s Secret owner L Brands, the Post reported.
Kristen Norman addressed the move on her Instagram page, writing "so long" to the estate.
"You were all-consuming and bloody demanding these last 10 years, and you damn well almost killed me a few times lately but boy oh boy, I never EVER will forget you and all the memories you gave me, my family & my friends," she wrote.
However, they will still own another home in Florida since, days after selling "Tranquility," the couple paid $12.2 million for an abode about 30 minutes away in the Old Palm Golf Club, The Palm Beach Post reported.
The 11,837-square-foot home includes six bedrooms, seven bathrooms and two half-baths, according to the former listing.
The double-lot property sits by a nice pond at one end of the club’s 19-hole course. It features resort-like amenities with a large pool, swim-up bar, summer kitchen, cabanas and a tennis court. The property also includes a guest house.
