Jeremy's antics appeared to amuse his girlfriend of ten months as she could be seen giggling while he struggled to remove his jacket, as they arrived for the party in Richmond Park.

The Grand Tour frontman took a break from filming for the high-octane Amazong Prime show as he ditched his jacket at the bash, with Lisa looking effortlessly chic in a blue checked dress.

Jeremy, who divorced his second wife Frances Cain in 2014, made his first red carpet appearance with Lisa last September.

Jeremy recently admitted his girlfriend told him to stop being 'horrid' to contestants while hosting Who Wants to Be a Millionaire?

The star was recruited by ITV to act as question master for one week of episodes to celebrate the popular show's twentieth anniversary, replacing former host Chris Tarrant.

He revealed that no-nonsense approach to quizzing did not go down well with his other half.

He wrote in his Sunday Times column: 'I always said if I'd been in Tarrant's shoes, I'd snarl and snap at hopeless contestants for wasting everyone else's evening.

'I tried it on the first show and afterwards my girlfriend was cross with me because I'd been "horrid".'

Clarkson's hosting style divided viewers at home after the first episode was broadcast.

Many on Twitter slammed him for being 'rude and insulting' to contestants and letting his 'massive ego' get in the way - yet others thought he was 'amazing' and 'funny.'
