Last Monday, the world finally got to see how some of the funniest people in entertainment make fun of Justin Bieber in Comedy Central, and Natasha Leggero's roasts have become quite epic in themselves, as many await for what she's about to say - but did she steal someone else's jokes?

The episode featuring some of the biggest funny people in entertainment (the lists includes Kevin Hart and Hannibal Buress), Natasha Leggero's roast abilities were also tested at the time, as she appeared on the Comedy Central show for the second time, following last year's Roast of James Franco.

Recently, it was reported that Jeff Ross, known as "The Roastmaster General," had asked Bieber's ex Selena Gomez for advice before the show, and that she'd given him a few pointers about the Canadian star, who ultimately apologized to audiences for his behavior - but now, right before the air date, it's Natasha Leggero's roast making news.

According to The Daily Mail, the Natasha Leggero roast issue came weeks after the actual filming of the episode, as she was recently a guest in "Midnight" along Ross, and the show's host, Chris Hardwick, asked them which stingers they'd failed to use during the Bieber episode.

"Jeff Ross looks like someone put a butter sculpture of Mr. Clean in the microwave," was Natasha Leggero's roast to the person next to her on the show, prompting controversy, as it had the same structure as a joke Pete Davidson had said during the taping of the show earlier this month.

"You look like someone put Seth Rogen in the microwave," Davidson had told his fellow comedian during the taping a couple of weekends ago.

Davidson, the 21 year-old SNL cast member, prompting called out Leggero on Twitter, causing the comedienne to quickly apologize, Just Jared reports, saying she'd "forgotten" about the original joke.

Are Natasha Leggero's roast abilities waning?
