And just when I thought this kid couldn’t make me laugh.

Justin Bieber was in Glendale, Arizona Saturday kicking off his ‘Believe’ tour, when he was suddenly struck with some type of illness. I guess he isn’t getting his Flintstone vitamins to help his immune system combat with the change in weather.

In the video, you can see Justin turning from his fans to VOMIT ON THE STAGE a couple times right before he runs off and has his backup dancers finish their routine. At least when Rihanna felt as though she was going to throw up at her concert she ran off stage beforehand. This boy really needs to learn about the warning signs of regurgitation.

The young pop-singer later tweeted (sorry for no screen shots; I’m at work):

Great show. Getting better for tomorrow’s show !!!! Love u

And …. Milk was a bad choice! Lol

Yeah, blame it on the milk Justin. You know Selena got you pregnant.

Check out the video after the jump and laugh and/or gag with me.
