She apparently recently split from her teenage beau YBN Almighty Jay.

And Blac Chyna went stag to the launch party of her pal Amber Rose’s line with the plus-size clothes company Simply Be in Los Angeles on Wednesday.

The 30-year-old mother-of-two flashed her enviably trim midriff beneath a cleavage-baring pink crop top with full sleeves and a zigzag motif.

Chyna, sporting a wavy platinum blonde hairdo, slipped into a pair of trousers that matched her top and balanced on dull gold platform shoes.

Caking her face in a thick layer of makeup including a glistening slick of ɴuᴅᴇ lipstick, she added a splash of glitz with a jeweled double-necklace and a watch.

She has yet to publicly comment on her breakup from YBN Almighty Jay, which he announced on social media on Tuesday of this week.

But insiders ‘close to’ her have told TMZ that she was suspicious the 18-year-old rapper may have impregnated someone else.

TMZ did get in touch with some YBN Almighty Jay insiders as well, who said – in the website’s phrasing – ‘there’s no confirmation yet that he’s got a kid on the way.’

DailyMail.com has reached out to a representative for YBN Almighty Jay for comment.

TMZ’s Chyna sources claim she got exasperated with YBN Almighty Jay’s behavior, which allegedly included messaging other women online, as well as spending time after his concerts with multiple female companions.

The breakup, according to these insiders, occurred roughly a week before YBN Almighty Jay made it public online.

To hear the gossip website tell it, the couple had also been frequently quarreling, and Chyna was ultimately the one to call it a day on the romance.

YBN Almighty Jay told No Jumper in March that he met Chyna on Christian Mingle and that he declined to wear condoms, saying: ‘I don’t wear rubbers… I wouldn’t f*** a b**** I wouldn’t wanna get pregnant, so I don’t – I don’t – you know what I’m saying?’

He broke the breakup news on his Insta Stories this Tuesday, writing: ‘@blacchyna & I Are No Longer Together’. That day, he deleted the post.

About a week ago, Chyna posted a swimsuit pH๏τo to Instagram and showed off a tattoo that appeared to read: ‘Jay’ in the crook of her left arm.

There was recently a swirl of rumors that Chyna was pregnant by YBN Almighty Jay after she was glimpsed with a bit of a bulge beneath her dress.

However, TMZ quoted insiders who dismissed these claims and said that the woman born Angela Renee White had just been, to use the website’s term, ‘bloated.’

The rapper also known as Jay Bradley asked Chyna: ‘Will You Marry Me?’ on Instagram in April – though it is not entirely clear whether or not he was joking.

Chyna declined to publicly respond to this message, and the fourth finger of her left hand has been bare in the intervening time, which suggests either that the proposal was just for laughs or that she turned him down.

Yet judging by the fact they kept being spotted out together, the pair, who were first linked in February, had evidently kept the romance going until recently.

The erstwhile reality star sH๏τ to public notoriety via her relationship with Rob Kardashian, with whom she shares a one-year-old daughter called Dream.

Chyna also has a five-year-old son called King Cairo by the rapper Tyga, 28, who in a bizarre twist used to date Rob’s half-sister Kylie Jenner, 20.
