Hilary Musser built a waterfront dream mansion … and now she’s ready to flip it for millions … TMZ has learned.

The “Members Only: Palm Beach” star has officially listed a jaw dropping waterfront mansion she custom built herself in West Palm Beach and the asking price is a cool $42.5 MILLION.

The estate has been featured on the Netflix series, where viewers have watched Hilary renovate and develop the mansion over an extended period of time and now, the project is finally complete and officially ready for its next high-profile homeowner.

The ultra-luxury estate quietly hit the market at the end of December, and it’s already turning heads for all the right (and outrageous) reasons.

The place features a second story pool and spa with 180 degree water views, an outdoor cocktail bar, and multiple outdoor kitchens built for nonstop entertaining. Inside, there’s a private movie theater, wine room, full spa, and not one but TWO full kitchens decked out.

Boat people, listen up … the property comes with a 100 foot deep water dock capable of handling large yachts, making it a true waterfront flex.

Location wise, it’s prime real estate … just minutes from Palm Beach Island and Palm Beach International Airport, perfect for anyone bouncing between private jets and boats.

Robert F. Kennedy Jr. may have put steak near the top of the food chain … but even he knows President Donald Trump eats like a stoner on death row.

The Health and Human Services Secretary opened up about his boss’s outrageous diet during an interview with Katie Miller — the wife of Homeland Security Advisor Stephen Miller — on her podcast.

When asked, “Who has the most unhinged eating habits?” RFK Jr. knew immediately … “The president.”

According to RFK Jr. … “He eats really bad food, which is McDonald’s and candy and Diet Coke. He drinks the Diet Coke at all times. He has the constitution of a deity.”

And just wait until you hear Trump’s reasoning … the same brain that pondered whether we should take injections of disinfectant to treat COVID-19 came up with a theory that food from big corporations is safer.

“He trusts it,” RFK Jr. said. “He doesn’t want to get sick when he’s on the road.”

“Sinners” writer and director Ryan Coogler turned a night of celebration into heavy reflection … getting visibly choked up as he called attention to the killing of Renee Nicole Good on a Minneapolis street by an ICE agent last week.

During the National Board of Review Awards gala in NYC Tuesday night, Ryan — accepting his win for Best Original Screenplay — didn’t mince words. He explained he was distracted, as his heart wasn’t in New York at all … it was in Minnesota, where tensions have exploded since Renee was shot and killed last Wednesday.
