Cara Delevingne refuses to ''get naked'' on screen.

The 21-year-old model - who is pursuing more acting roles after making her TV debut in 'Timeless' - claims she's been offered numerous parts in films but has rejected the scripts as they require her to strip down to her birthday suit.

She said: ''I've had lots of film offers where I have to get naked. But I do have morals - and I want to keep them.''

The blonde beauty - who is believed to be dating 'Fast and Furious' actress Michelle Rodriguez - confessed that although she enjoys modelling and is thankful for the opportunities it's presented her with, acting is her first love.

She said: ''The first time I went on stage, I just wanted to be an entertainer, a performer.

''It's all I wanted - so doing this show is like living a dream. I prefer acting to modelling, although that's where I started and I'll never turn my back on it. I thank it for everything I've done.''

Cara also admitted that she pursued a career in acting before she started modelling for brands such as Burberry and Chanel, but wasn't thick-skinned enough to handle being turned down.

She revealed: ''I started auditioning for movies before I started modelling but I couldn't deal with the rejection. When I got turned down for something it would take me weeks to get over it. Now I still care but it's less of a hit.''
