Sadly, it was just a false alarm and Pro Green was actually making fun of the Made In Chelsea star and her food baby.
It is bad to say we're a tad disappointed?
Professor Green (real name Stephen Manderson) and Millie are currently holidaying overseas and during their dinner date yesterday evening, the rapper couldn't resist winding up his missus - and us!
Taking to Instagram, he shared a photo of Millie - who looked gorgeous in her girly getup - holding onto her stomach. Usually the tell-tale sign of a pregnancy, or so Professor Green led us to believe, as he cryptically captioned his snap: "We have an announcement to make..."
Not surprisingly, the star's followers went into overdrive, sharing their excitement on the post. One user commented: "Can it be?" While another said: "OMG, is this true?"
And after letting his fans sweat for a little bit, Pro Green finally put them out of their misery, revealing: "Millie is pregnant... With a food baby."
Since tying the knot nearly two years ago, the couple are constantly finding themselves batting off pregnancy rumours, and it's not the first time Professor Green has joked Millie is expecting.
After quashing claims Millie was pregnant back in February, he then shared a photo of Millie sporting a rounded tum after she had eaten, telling followers: "Well this isn't going to do anything but fuel rumours @camillamackintosh."
Cor, a girl and her food bloat just can't catch a break!
Despite Professor Green joking about his wife falling pregnant, it's not entirely something that is off the cards.
Millie has openly spoken of her wish to start a family with her husband, revealing she is hoping to fall pregnant by the time she is 30. And considering she's now 25, she might not have that long to wait!
"I want to be a young mum," she confessed last year. "I'd like to have kids by the time I am 30."
She even revealed she and Pro Green already have a few "traditional, but unusual" names picked out already, explaining she would like one or two kids of each sex.
Millie and Professor Green first got together while she was still starring on Made In Chelsea. The pair later married at Babington House in Somerset in September 2013.
