"He's a tiny little baby!" she said, referring to the Canadian pop star with whom she shared the stage on Grammy night. "I would've loved to push him around on stage in a carriage."
While she may have been kidding, Ke$ha's joke was not funny to Justin's die-hard fans. Beliebers flooded fansites with anti-Ke$ha comments, which led her to issue an apology to JB via Twitter on March 21.
"Dear justin b i am so sorry if my bad joke has hurt your feelings," she tweeted. "U r obviously so talented and i would never mean to offend u. I think u r rad."
Known for her party girl persona and whatever goes attitude, the 23-year-old pop vocalist probably didn't mean to come off so harsh, but she certainly didn't watch her words either. Justin never publicly commented about the remark, so we think he's still cool with Ke$ha. Hopefully, his fans will let the comment slide, too.
