"Take your top off," Judge urged the other housewives as she jumped into the beautiful blue water on the island of Moorea, where the women continued their Tahitian girls' trip.
The wives stayed in private huts over the water, but not everything was private.
"There's people staring at you," said Heather Dubrow, covering up Judge with a towel.
"It looks like you got sun," Meghan King Edmonds told Judge later at dinner, before adding, "That's because you were naked."
Said Shannon Beador: "Vacation Shannon will never be topless because I breastfed for three years of my life."
But Lizzie Rovsek won't have to worry about breastfeeding for a while, after Vicki Gunvalson made her take a pregnancy test (two actually) to see if the housewife was expecting or not.
"Hurry up and pee," Gunvalson urged Rovsek who locked herself in the bathroom after dinner.
"I've got major stage fright going on," said Rovsek as Gunvalson yelled through the bathroom door.
"Of course you're not pregnant," said Gunvalson when the tests were revealed to be negative. "You just didn't want to whoop it up."
"I'm actually relieved," Rovsek replied. "Vicki, start the fun bus."
But the fun bus stalled when the wives went swimming with sharks and stingrays.
"I'm not going in!" screamed Gunvalson, who booked the excursion.
"They'll probably eat one of my boobs," said Judge, whose fake ones were later felt up by Beador. "I'll be boobless again."
"A stingray feels like leather … slimy leather," said a scared Beador, who got a big assist from Dubrow to pet it. "Swimming with sharks and stingrays. Check!"
But the fun bus got restarted later that night, as Gunvalson commandeered a golf cart and literally drove it into the hotel bar.
"Don't ever ask me to drive to the bar," she laughed. "When I drive, you'll always get the best parking spot."
And the fun bus kept rolling – while half the wives went to dinner, Gunvalson, Beador and Judge partied it up.
"The whoop it up dream team is here," said Gunvalson, who ordered fireball shots but instead got straight shots of vodka. "Cheers to Tahiti!"
"Cheers to whooping it up!" said Beador, before the three wives jumped into the hotel pool – this time, however, Judge was fully clothed.
