When it comes to finding out your baby's sex before they are born, some parents simply cannot wait while others hold out for the big reveal.
Neither is right nor wrong, but for some not finding out can leave them feeling a little anxious - exactly how Pink's husband, Carey Hart, is feeling right now.
Talking to People, the 41-year-old admitted that he would love a boy so daughter Willow Sage, five, won't have any competition.
"We got one princess, so hopefully we'll have a little guy coming," the motorcycle racer said. "I don't want any competition for my daughter."
"I'm nervous for what it's going to be."
However, that's not the only reason that he is feeling a little anxious.
"It's been a while since we've had a baby around the house," he continued.
"It's going to be really fun."
37-year-old Pink, whose real name is Alecia Moore, revealed her wonderful baby news on Instagram, posting a photo of herself cradling her blossoming bump with her eldest child.
“Surprise!” the Raise Your Glass singer wrote in the simple caption, to the delight of her legion of devoted followers.
