Holly Willoughby shared the oddest test for guessing a baby's gender

"I tell you, it’s always right!"

Holly Willoughby just shared the most bizarre test for predicting whether an unborn baby will be a boy or a girl.

The This Morning presenter was commenting on a photo of Serena Williams' pregnant body.

The tennis player shared the photo on Twitter, asking her followers whether they thought she was having a girl or a boy.

Holly explained that you can tell by placing your hands at the sides of your bump and said that if your hands lean inwards, it's a boy but if your hands veer outwards, it's a girl.

She said that based on Serena's picture, she reckons she's expecting a girl.

Holly Willoughby's trick for telling whether you're having a boy or a girl.

“It’s hard to tell in a photo but if you’re pregnant at home do it, I tell you, it’s always right, it’s that shape," she said.
