Blac Chyna flashes her ample bosom and bare midriff in beaded bra as she posts sexy Instagram snap... amid custody battle rumors

She's rumored to possibly be going up against former fiancé Rob Kardashian for custody of their four-month-old daughter Dream.

But Blac Chyna showed no signs of distress as she took to Instagram in one of her latest adverts for her beauty line, Lashed Cosmetics, on Wednesday.

The 28-year-old video vixen put on a very busty display wearing a low-cut beaded bra which flashed her ample bosom and bare midriff.

The reality star posted a series of social media snapshots of herself posing up a storm for an ethereal beachside photo shoot.

Her plunging nude-colored bra was adorned with intricate rhinestone detailing throughout.

She teamed the eye-catching undergarment with a long flowing white skirt which included a thigh high slit.

Blac opted for a long blonde look styled in soft waves which cascaded effortlessly past her shoulders.

Meanwhile, Chyna's heavenly campaign comes on the heels of rumors that Rob might wind up facing off against Blac over custody of their daughter Dream, who was born in November. 

They dramatically split in December, Rob posting a Snapchat video bewailing her absence while wandering through their empty house, but reunited soon after.

There are conflicting rumors about whether they've split again since, and though neither of them's confirmed as much, a source has dished to People about conflict over Dream in an article that ran earlier this week.

'Rob wants dual custody of their child and Blac Chyna is giving pushback,' said the source, adding: 'They are still figuring things out but she will certainly do whatever it takes to have Dream be with her for the majority of the time.'

Meanwhile, Rob's mother 'is backing Rob up 100 percent and won’t let Chyna get away with anything that’s less than fair.'

Yet Chyna was amicable this Friday, posting an Instagram photo of herself and Rob together and wishing him: 'Happy Birthday' in a caption with a shamrock emoji.

She also turned up in a pink Land Rover to his 30th birthday party that evening, which also happened to have been St. Patrick's Day.

Covering the April issue of Cosmopolitan South Africa, she told the magazine she and Rob 'love each other and we're fighting for each other.'
