James Martin was left squirming when he was grilled on rumours he's set to present the next series of 'Top Gear'.

The 44-year-old culinary mastermind has been attached to the hosting role on the revamped motoring show since Chris Evans dramatically dropped out two months ago.

But, although he refused to divulge whether he's been approached by bosses, he couldn't stop his cheeks from glowing an embarrassing shade of red when Rylan Clark-Neal challenged him on 'This Morning' on Friday (12.08.16).

James said: "I'm well known now so I can get to go backstage in the lovely hospitality area. No I'm not saying it, I'm staying silent. This show stresses me out enough."

Not ready to give up on his exclusive just yet, the 'Big Brother's Bit on the Side' host continued to push.

He said: "If you were asked would you consider it?"

Refusing to give anything away, James turned his head away and attempted to move on to the next segment.

Meanwhile, 'Top Gear' has been the hot topic of conversation since the radio presenter quit in June - a year into his three-year contract - after the final episode of the revamped show pulled in its lowest viewing figures since 2002.

Although rumours are swirling about who will take Chris' place, it's believed Matt LeBlanc - who co-hosted the last series - will return as the solo presenter later this year.

A source said recently: "Matt is going to get the big job on his own. There are already active negotiations and he's almost certain to sign now that he doesn't have to work with Chris. Chris won't be replaced but Matt will become the star presenter surrounded by the existing team."
