Kristen Stewart kept a low profile when she arrived at JFK on Monday -- so low that when we saw her, we thought she might just be a teenage boy!

Going incognito with a backwards hat and shades, the "Twilight" star seemed like she wanted to stay away from drawing any attention to herself.

The 24-year-old has been enjoying some downtime after filming back-to-back movies.

The 24-year-old actress is in the Big Apple to attend the premiere of her latest film, Clouds of Sils Maria, which is playing at the New York Film Festival on Wednesday.

Later this year, Robert Pattinson's former flame also stars in Still Alice, alongside Julianne Moore, who plays a woman who is diagnosed with the early onset of Alzheimer's in the film. Kristen takes on the role of her daughter, dealing with the devastating illness.
