Congratulations are in order for Amanda Seyfried!

The Hollywood actress is expecting her first child with fiancé Thomas Sadoski, her rep confirms to E! News. 

While attending the launch for Givenchy's new Live Irrésistible fragrance Tuesday evening, Amanda debuted her baby bump in a black mini dress. She completed her look with matching heels and her hair pulled back.

Back in September, E! News confirmed that the actress got engaged to her boyfriend and The Last Word co-star.

Although the two stars tried to keep their relationship private, the pair reportedly couldn't help but share their engagement news with family and close friends.

And while they aren't ones to walk countless red carpets together, they recently shared part of their Halloween celebrations on social media. How does a trip to Universal Studios Hollywood sound for Halloween Horror Nights?

"Thanks for the most entertaining Halloween yet @unistudios @horrornights #UniversalHHN," Amanda wrote on Instagram after photoshopping her beloved dog in the photo. "(If @finnsite had actually attended this is how the photo would have looked)."

Back in August 2015, Amanda expressed her interest in wanting to have kids. While talking to Marie Claire UK, the actress joked that she needed to "get on it."

"I keep feeling like my eggs are dying off. I need to get on it… I want a child. Badly. I want to be a mother, badly," she shared with the publication. "That's what I feel. I've been feeling it for like, two years. I'm not ready but nobody's ready. It changes everything… so how you can ever be ready for that?"

Romance rumors sparked between Amanda and Thomas early in the year when they were spotted walking back to their trailers together in Pasadena, Calif. And while they first met after working together on the off-Broadway show The Way We Get By, things didn't heat up until they reunited for the film The Last Word.

Congratulations to the happy couple!
