Neve Campbell preg with #2

Party of four! Neve Campbell is pregnant, Us Weekly can exclusively reveal, expecting her second child with her longtime boyfriend JJ Feild.

The Party of Five and Scream series alum, 40, stepped out on Sunday, Sept. 21, showing the slightest hint of a baby bump. She went casual for the day in the park in Hollywood, wearing a loose, striped T-shirt with cropped boyfriend jeans and flip-flops.

Campbell spent the sunny afternoon in the park with her first child, son Caspian, 2. The Mad Men guest star and her actor love welcomed the little boy in August 2012.

"They've always wanted more than one child," a source tells Us Weekly exclusively. "They want Caspian to have a sibling."

Though the stars are very private with their personal lives, Campbell went on The Talk in December 2012 and spoke about her son and his unusual name. "I liked the idea of a unique name," explained the star, whose own name is her mother's maiden name. "It's nice having something special and different and so I wanted something like that for our son."?
