Amanda Seyfried and fiance Thomas Sadoski pregnant with first child

Actress Amanda Seyfried is going to be a mother and is set to welcome her first child with fiancee Thomas Sadoski.

The actress revealed that she's pregnant by debuting her baby bump during the launch of Givenchy's new Live Irresistible fragrance, reported Ace Showbiz.

Seyfriend, 30, looked stylish that night as she flaunted her belly in a sheer mini dress. Pulling her hair into a ponytail, the Mean Girls star teamed her simple black outfit with strappy heels of the same colour.

This will be the first child for both Seyfried and Sadoski, who began dating earlier this year while working together on The Last Word. The actors then got engaged a few months ago.
