A man accused of stalking Black Swan star Mila Kunis has pleaded not guilty to felony charges.

Stuart Lynn Dunn, 27, was arrested last month by Los Angeles police officials after allegedly spending three consecutive days at a gym repeatedly trying to make contact with Kunis.

The incident came four months after he was detained by police for breaking into Kunis' West Hollywood home.

The actress won a restraining order against him.

Dunn will return to court on August 1 for a pre-trial hearing.
