Matt Le Blanc is reportedly ready to quit Top Gear if Chris Evans stays on as host.
Chris Evans and former Friends actor Matt LeBlanc took over hosting of the motoring programme earlier this year, after Jeremy Clarkson, James May and Richard Hammond departed the series.
After the revamped show premiered in May, it received mixed reviews from fans, with many criticising Chris' "shouty" presenting style.
It's been plagued by falling ratings - just 2.34 million people tuned into last week’s episode, the lowest audience posted by the show's former team, led by Jeremy Clarkson, was 2.36 million in June 2003.
And it's also been dogged by rumours of on-set tension between the hosts.
And it appears to be getting too much for Le Blanc as a Top Gear source reported to The Sun that the actor is contemplating quitting the show.
According to The Sun's source, LeBlanc "has already indicated that he won’t continue on any further series if Chris remains a part of it. And he is far from the only one who isn’t happy."
LeBlanc's contract has him signed up for two more seasons of Top Gear, so it seems the rumours may not be entirely true.
The 48-year-old has been open about the fact that he took up Top Gear presenting duties because he needed a job.
His reps have since insisted the claims are "not correct".
While a spokeswoman for Matt told the Sun: “Nothing has been discussed or decided," a rep has since told Mirror Online: "It is not correct."
Meanwhile, BBC boss Alan Tyler, the acting controller of entertainment commissioning, has insisted that executives are pleased with the show's performance so far - despite ratings falling each week.
Speaking to the Mirror, he said: We are four episodes into the new Top Gear era with its new presenting line up, and remain really pleased with the way the series is performing."
