Jennifer Hudson was the woman of the night after winning the Favorite Humanitarian Award at the People's Choice Awards Wednesday, but the ruckus she reportedly caused backstage is what has people talking.

Apparently Hudson had a former close friend of hers, singer/rapper Kraven Tionne Williams, who goes by Lord Kraven, kicked out of the Nokia Theatre!

An eyewitness said, "Jennifer loudly threatened 'Either he leaves or I leave' and was waving her finger in the face of a security guard!"

That's when Williams was told to leave before "the situation continued to escalate outside the main auditorium and required the assistance of LAPD."

He did confirm with TheYBF.com that he was indeed asked to leave. But, just like the rest of us, he wants to know why. He took to his Twitter Friday to confront Hudson.

Williams wrote, "OMG! I can't believe THIS! JENNIFER HUDSON, look what YOU HAVE CREATED! This is absolutely ridiculous!"

While he said he doesn't know what caused Hudson to want to kick him out of the awards show, he might have an idea. Back in April of 2012 --when the man convicted of murdering Hudson's mother, brother and nephew was on trial-- Williams did an interview with Headline News and credited her relationship and faith in God as what will bring her through it all.

In the interview Williams said, "We both grew up in the church so I believe that she has tapped into that strength of [God] and I believe that has what sustained her then and now."

The insider said, "Before then Jennifer and Lord Kraven were close, but ever since then she has declared war against him."
