Blac Chyna wants to get something ''off my chest'' about her fiancé Rob Kardashian.

The 28-year-old model - who has recently given birth to her first child Dream with the 'Keeping Up With the Kardashians' star - has taken to social media to reveal she has got ''some things'' she wants to reveal about her 29-year-old partner, as she posted a cryptic message on her social media account.

The television personality shared a picture of a note she had penned to her Instagram account on Thursday (15.12.16), which read: ''I have some things I want to get off my chest about how i truly feel about Rob ... (sic).''

And the brunette beauty - who also has four-year-old son King Cairo from her previous relationship with 'Rack City' rapper Tyga, who is now dating Rob's youngest half-sister Kylie Jenner - simply captioned the post with a few ellipses.

She wrote: ''... (sic).''

Although it is unknown whether Blac' forthcoming confession will see her slam or praise the Arthur George sock designer - who proposed to Blac in April only four months after the pair started dating - it is known the pair had a rocky patch prior to having Dream.

And earlier this year it was reported the couple hadn't spoken to one another for ''months'', and had reportedly ''split'' in September, according to TMZ.

News of problems in the pair's relationship may not be a big shock as it was previously claimed their reality show was driven by their frequent rows.

Production sources claimed they fight over a variety of issues, from Rob's weight, to posts on social media, to money and fame, and very few things are not filmed.

However, the couple have recently confirmed their reality show 'Rob & Chyna' has been renewed for a second eight-episode series in 2017.

Rob and Chyna are currently living in a lavish mansion owned by Kylie Jenner, Rob's half-sister, in order to be closer to his family.
