Perma-kitten Lil Bub took the internet by storm last summer. Since then the feline, who has a bone condition which leaves her paws deformed and her mouth open and will stay small because she's a dwarf, has been viewed millions of times on YouTube and is a force on Facebook and Twitter.

The adorable cat recently branched out into the world of film, starring in 'Lil Bub & Friends.' The documentary also features other internet kitty sensations like Grumpy Cat and Keyboard Cat.

The film has been featured at the Tribeca Film Festival, which is running this week. As you can see, Lil Bub spent a little time with the festival's founder Robert De Niro during the event.

Will hanging out with Bobby De Niro go to Lil' Bub's tiny head and cause her to demand a bigger trailer and better craft services on her next YouTube shoot? Only time will tell. For now check out some more photos of the fetching furball with the acting legend. (The other fellow in the shots is her owner Mike Bridavsky.)
