Amanda Seyfried is pregnant!

The actress announced that she is expecting at Tuesday’s Givenchy press launch for their new Live Irrésistible fragrance, which she is the spokesmodel for. At the event, Seyfried, 30, was dressed in a Givenchy black mini dress that showed off her tiny baby bump.

This will be the first child for Seyfried and her fiancé, actor Thomas Sadoski.

PEOPLE confirmed the couple got engaged in September. The actress was pictured wearing a silver band on her left ring finger while out and about with her beloved dog Finn in New York City.
