(Cover) - EN Movies - Rosario Dawson has teased she has a "pretty big head".

The 32-year-old American actress is best known for serious roles in movies such as Eagle Eye and Seven Pounds, although she's currently promoting family comedy Zookeeper, which she stars in alongside funnyman Kevin James.

The stunning actress feels at ease in the comedy genre as well as in dramas, and has joked that she has a rather large ego after making Zookeeper, which is released in the US today.

"I've got a pretty big head now," laughed the star at the film's Los Angeles premiere.

"I feel like I could do comedies all the time."

Rosario enjoyed her time making the picture about a group of zoo animals who decide to help their kind keeper, played by Kevin, find love. However, she admits to sometimes finding it tough hanging out with comedians. The beauty considers Kevin, 46, "sweet" and "loving", although she thinks comics can sometimes be depressing.

"I've spent a lot of time with comedians over the years and I love some comedians, but they can tend to be pretty dark, negative people," she smiled. (C) Cover Media
