Blac Chyna Nearly Busts Out Of Plunging One Piece In Glam Photo... After Kardashians Gang Up On Her

The Kardashian sisters vowed to keep an eye on their brother Rob after his fiancee threatened to dump him during a teaser for Sunday's new episode of Keeping Up With The Kardashians.

But the family tension doesn't seem to have gotten to Blac Chyna, who tends to play it cool even when her relationship with the black sheep of E! seems frostier than ever.

On Wednesday the 28-year-old reality star posted to Instagram a photo of herself in a plunging black bathing suit - which nicely showed off her tattoos - as she posed next to a hot tub.
