A new report lends more credibility to rumors that new Top Gear presenters Chris Evans and Matt LeBlanc aren't exactly best buddies.

The latest out of England comes courtesy of The Sun. The report cites unnamed sources in the battle between Evans and LeBlanc, with the latter saying that he will leave the show unless Evans is replaced.

“The team does not gel and the atmosphere between the presenters is decidedly frosty," the source reportedly said. LeBlanc is said to have criticized Evans for his rude attitude toward the production team, a complaint also levied periodically at former frontman Jeremy Clarkson. The source suggested that the rest of the Top Gear team also feels the same way about Evans, who apparently doesn't socialize with LeBlanc or the other co-presenters outside of filming and that he is not interested in helping anyone.

Evans himself was the subject of drama well before this latest series even hit the airwaves. 

Filming for the current Top Gear series is complete, with the next season set to start production within a few months. 

"The big question now is who goes and who stays," the source told the British paper. 

Some changes are undoubtedly already under way, as ratings have dropped to their lowest levels since 2003. It was the on-screen camaraderie between the previous hosts—Clarkson, Richard Hammond, and James May—that changed Top Gear from a mere show about cars into a global entertainment success story.
