“Mamma Mia!” actress Amanda Seyfried is expecting her first child. The “Mean Girls” star sported a visible baby bump at a press launch for Givenchy’s new Live Irresistible fragrance on Tuesday.

The glowing 30-year-old artist wore a chic black dress at the event and made no attempt to hide the good news from press and paparazzi. Seyfried is expecting her first child with fiancé Thomas Sadoski. The “Jennifer’s Body” actress met Sadoski when they were acting in the play “The Way We Get By” in 2015. The duo reunited again on the set of the movie “The Last Word” earlier this year.

40-year-old Sadoski and Seyfried started dating in March, according to Entertainment Tonight. The couple got engaged in September and soon they will welcome a baby together. When she got engaged, People reports that the Pennsylvanian-born actress started wearing a silver band on her left finger while she was out walking her dog Finn in New York.

Sadoski has been married before. He tied the knot with Kimberly Hope. The couple divorced after eight years of marriage, according to Marie Claire.

Sadoski and Seyfried have made their relationship public with the latter often posting photos of her and her fiancé on Instagram. Furthermore, the duo have attended several events since they started dating.

Seyfried previously dated her “Mamma Mia!” co-star Dominic Cooper from 2008 to 2010 and then Justin Long from 2015 to 2015 before finally deciding to settle down with Sadoski.

The actress has many films lined up next year, apart from “The Last Word,” such as “The Clapper,” “Anon” and an untitled Nash Edgarton Project. She will also be seen in Showtime’s revival of “Twin Peaks” next year.

Seyfried has admitted to suffering from panic attacks and has Obsessive-Compulsive Disorder (OCD). She also suffers from stage fright.
