Justin Bieber Sorry for April Fools' Joke That Hailey Baldwin Was Pregnant

Justin Bieber and Hailey Baldwin

The singer said he is "a prankster."

Justin Bieber is saying sorry — for fooling his followers into thinking wife Hailey Baldwin was pregnant.

On April 1, Bieber posted prank photos on Instagram that suggested Baldwin was pregnant. He first shared a sonogram picture, followed by a photo of Baldwin on a doctor's table with her hands on her belly. Websites and news outlets speculated whether the new couple, married last year, were expecting. 

 But apparently not everyone was laughing.

The next day, Bieber apologized for his joke, saying he is "a prankster" and that it was "APRIL FOOLS."

"There’s always gonna be people offended, there’s also people who don’t take jokes very well," Bieber wrote on Instagram Tuesday. "I didn’t at all mean to be insensitive to people who can’t have children. A lot of people I know, their first go to prank on April fools is telling their parents they are pregnant to get a big reaction. But I will apologize anyway and take responsibility and say sorry to people who were offended."
