Her spokeswoman, Erica Gray, confirmed to The Associated Press on Wednesday that the 25-year-old actress is expecting her first child with husband Seth Gabel.
"I can't talk about the pregnancy too much," she was quoted as saying. "I'm a little superstitious."
Howard, who also starred in Shyamalan's 2004 film, "The Village," and Gabel, 25, were married in June.
She has a role in "Spider-Man 3," slated for release next year.
Gabel has appeared in the TV series "Nip/Tuck" and "CSI: Crime Scene Investigation" and in the movie "The Da Vinci Code." He has a role in the upcoming film "Running With Scissors."
