Just after her friend Beyoncé announced she was expecting twins via an OTT Instagram shoot, Miss Minaj brought her own pregnancy showcase to the social media site.
In a picture shared with her 73.2 million followers, the 34-year-old showed off a massive bump in a sheer black vest.
The racy lingerie also exposed a whole lot of sideboob, but full focus was on Nicki's blossoming belly.
Nicki captioned the pic: "ATBIMS. y'all so childish OMGSKLKZFCBNUF - I was gonna wait to share the news but…"
The photograph sent her fans into meltdown, mainly because nobody could agree whether the pic was legit or not.
Many comments read: "Congratulations", while others asked: "Who's the father?"
However, many others insisted the photo was faked, with a lot of comments pointing out that the pic was Photoshopped.
Considering Nicki previously posted a picture of herself rocking a washboard-flat tummy in a high-cut swimsuit, we're gonna go with that theory.
Plus, the "ATBIMS" reference in the caption means "all these bitches is my son" – a line that features in multiple Nicki songs.
Before they broke up, rapper Meek Mill teased that they were expecting a baby, writing on his Snapchat: "I ain’t tell ya’ll about her being preg… nvm lol."
The message was soon deleted.
Last week, Kim Kardashian also sparked rumours she could be pregnant after retweeting a provocative message.
