Ooops!
When you find out the gender of your baby before you give birth, it can be hard to keep it under wraps.
And it looks like two expectant celebs were so excited about their impending arrivals, that they let their gender slip.
Vogue Williams accidentally revealed her baby's gender on RTÉ's Cutting Edge.
Last night's show saw the reality star quizzed about diet and exercise during her pregnancy.
She said: "I’m not eating for two people. My baby is the size of an heirloom tomato today, I Googled it."
Host Brendan O'Connor asked: "A little tomato. Is he happy in there right now on television?"
Vogue replied: "He’s delighted with himself."
Brendan then responded: "Is he? So it’s a boy?"
Vogue realised her gaffe, put her head in her hands and loudly proclaimed, "I hate you!"

Meanwhile, Prince William's dropped a massive clue about the gender of his little one.
The Mirror reports the soon-to-be dad-of-three let slip that he and his wife Catherine are expecting a boy.
The paper says the Aston Villa fan was spotted celebrating Jack Grealish's goal against Cardiff City on Tuesday, where he told other supporters, "I'm going to insist the baby is called Jack."
He then pause before adding, "Or Jackie."
