Justin Bieber gave his grandmother a little an eyeful when he decided to play a Thanksgiving prank.
Here’s what happened:
Our sources tell us JB had been staying at his granny”s house during the holiday … and slept in a little too late on Thanksgiving morning.
Bieber finally woke up after hearing family and friends stirring around the house — so he thought he’d prank ’em … by grabbing his guitar and playing a naked set a la Jenny from “Forrest Gump” (‘memba that?).
We’re told birthday-suited Bieber went right up to his grandma and started belting out some impromptu lyrics … like, “I Loooove you grandmaaaa … how are youuuu … helloooo grandma.”
We’re told G thought it was pretty funny — and everyone in the home was cracking up — but granny begged the pop star to get back in his room to put some damn clothes on, stat.
We never thought he’d be involved in this type of nude picture scandal.
