Justin Bieber didn't fool too many Beliebers with his April Fool's Day joke yesterday but still, fans were questioning whether his wife Hailey Baldwin might actually be pregnant.

After posting a sonogram pic and then snaps of Hailey apparently getting a gynecological exam and holding her belly, some fans were actually PISSED over the ruse. They said it wasn't appropriate given some people's struggle with fertility issues. Uh ... what the heck does that have to do with his joke?!

One astute fan emailed us and pointed out the supposed gynecological exam was staged at Bieber's "brain health center" the Amen Clinic.

Jailey lovers were demanding to know the truth and Justin finally put the speculation to rest with the below Instagram with the caption, "Wait omg is that a,,, APRIL FOOLS." Okay, FOOLS chill out a little and have a laugh!
