Cara Delevingne has made friends with her ''idol'' Jack Black.

The Burberry model has plenty of showbiz friends - including Rihanna, Rita Ora and Harry Styles - to keep her company, but now she has another name to add to her phone book after finding the time to hang out with the Tenacious D star at Comic-Con and it would seem like the pair got on very well.

Cara posted two selfies on Instagram to mark the occasion.

To accompany one of her photos, she wrote: ''I met my idol today... the one and only JACK BLACK!! I think we were separated at birth. (sic)''

The 'School of Rock' actor looked equally pleased as he smiled for the camera with Cara.

The pair were both at Comic-Con in San Diego, California on Saturday (26.07.14), with Jack in attendance to promote his new film, 'Goosebumps' which is based on the book series of the same name by R.L. Stine.

On the other hand, Cara was having fun posing with the 'Ghostbusters' props. Dressed in denim dungarees, the 21-year-old model sat on the bonnet of the Ecto-1 vehicle for her Instagram photo.

She captioned the picture: ''Who you gonna call... I feel like such a tourist right now hahaha. (sic)''
