Brittny Gastineau has fun in the sun in Miami

Frequent Keeping Up with the Kardashians “costar” Brittny Gastineau was making a bit of a spectacle of herself while vacationing in Miami Beach over the weekend. E! News posted a video of her looking intoxicated at the Fontainebleau, fiddling with her thong cut-out bathing suit while leaning seductively over an outdoor bar.

Apparently a friend of hers made her the haute monokini, she wrote on her Instagram account. “Thank you @adamsaaks for making me this #sexy bikini love you #Mia,” she posted.

Later Mark Gastineau’s socialite daughter passes out for all to see on a chaise lounge. Though Brittny is pictured with a male, rumored to be model Eric Meier, at the hotel, it is most definitely not rumored off-again beau, L.A. graffiti artist Marquis “Retna” Lewis.

The two were rumored to be in a bustup in June that had Gastineau walking around with a black eye. They later released a statement saying while they disagree about the facts and circumstances surrounding the unfortunate incident, they hold no ill will toward each other.
