The cars on display were also looking suitably snazzy.
Transformers star Megan unveiled her own streamlined physique in a backless mint green dress as she turned out at a function put on by the motor firm to celebrate the 50th anniversary of the Jaguar E-Type.
She was joined by her husband Brian Austin Green, who she posed with happily.
The Jaguar E-Type was once described as the 'world’s most beautiful car' by racing driver Enzo Ferrari, the late founder of the Ferrari Italian motor brand.
Megan has recently finished filming the upcoming comedy Friends With Kids.
