Having already been through one pregnancy, you’d think Blac Chyna would know exactly what to expect now that she’s knocked up with her very own Kardashian.
But it seems one aspect of pregnancy came as a shock to the 28-year-old – weight gain.
Spending Saturday in with her son, King Cairo, she Snapchatted a weigh-in showing a set of scales with the numbers 163.2 on it.
She captioned the shot: ‘I gained 20lbs’ along with a distraught emoji.
It wasn’t that long ago though that the ex-stripper was defending her extra curves after she received nasty comments from online haters.
In a now deleted post, she wrote: "To all you people out here with negative comments and insecure words (obviously because you have nothing else to do but criticize the next) I AM HAVING A BABY!"
She went on: "If I comment on y'all pics and go in on them tired ass weaves or unblended a** contours I'll be wrong right?"
"It'll be tragic! So stop playing & Put Some Respeck on my name."
Blac, who shares her three-year-old son with ex Tyga, announced that she is expecting her second child earlier this month.
We're sure Kim Kardashian will be offering her future sister-in-law tips to get her pre-baby body back in no time...
