But he later followed up with another ultrasound showing a puppy instead of a baby, writing: "Wait omg is that a...APRIL FOOLS."
Fans have been quick to condemn the stars actions, calling the joke "insensitive", with one fan writing: "Justin Bieber doing an April fools' about Hailey being pregnant is actually so vile. It's nothing to joke about."
So Justin Bieber posts a pregnancy April fools and everyone’s laughing it off? I don’t care if you’re famous or not, if you pretend to be pregnant for a joke you’re an A class bellend xx

Fake pregnancy announcements for April Fool's Day have come under fire in recent years with many health professionals reminding people that it is far from harmless.
One particular post has been widely shared this week, highlighting statistics of miscarriage and infertility.
The post says: "This is not an April Fools' Joke! One in four of your friends will have lost a baby and one in six will be suffering with infertility".
