Blac Chyna has lost one stone in weight one week after giving birth to daughter Dream.

The 28-year-old American model welcomed the tiny tot - who she shares with Rob Kardashian - on November 10, and in only seven days ''postpartum'' the 'Rob & Chyna' star has dropped from ''192lbs to 177 lbs''.

The brunette beauty - who also has four-year-old son King Cairo with her former partner Tyga - took to social media to share the news of her drastic weight loss.

The star shared a picture of her on the weighing scales on Snapchat, which she captioned: ''From 192lbs to 177lbs (7 days postpartum) (sic).''

However, the television personality - who announced she was engaged to the 29-year-old 'Keeping Up With the Kardashians' star earlier this year - has revealed she still has just over 40 lbs to lose to reach her ''goal''.

She said: ''Goal 130lbs my starting weight b4 Dream (sic).''

And Blac isn't the only one who wants to shed the post-baby weight, as the Arthur George sock designer has admitted he needs to lose weight too.

Speaking previously about his shape, he said: ''[I need to] get back on it now cuz our baby is here. (sic).

''It's time for me to lose this damn weight already. (sic). ''

Meanwhile, the couple have taken to social media to gush about their new born baby, who Rob has likened to his late father Robert Kardashian who passed away when he was 16 years old.

Alongside a picture of Dream and the American attorney shared on Rob's Instagram account, he wrote: ''She's an exact copy. Pops sent us an angel. It's truly a blessing. He's happier than anyone on this day I'm so happy and thankful GOODNIGHT (sic).''

Whilst in another post he likened his only child's hairstyle to his 61-year-old momager Kris Jenner.

Speaking previously, he said: ''Look at your Kris Jenner haircut.''
