Kaia Gerber, 13, will play Stana Katic's character as a girl in indie movie Sister Cities.

The film will also feature Michelle Trachtenberg, Troian Bellisario and two-time Oscar nominee Jacki Weaver.

The casting news comes less than a week after Gerber secured a new deal with prestigious agency IMG Models.

The brunette, who made her modelling debut at the age of 10 for Young Versace, is now part of a roster that includes Candice Swanepoel, Miranda Kerr and Rosie Huntington-Whiteley.
