Liev Schreiber and his glowing pregnant girlfriend Taylor Neisen lead the stars at premiere of A Small Light in New York City

Liev Schreiber stepped out with his stunning girlfriend Taylor Neisen on Tuesday when they attended the NYC premiere of his new miniseries A Small Light. 

The Ray Donovan star, 55, and his gorgeous 31-year-old partner made their first public appearance five days after DailyMail.com exclusively learned that the couple are expecting their first child together. 

Schreiber looked dapper in a suave gray suit while Neisen draped her growing baby bump in a flowing dark brown dress.

The Emmy-nominated actor portrays Anne Frank’s father Otto Frank in A Small Light – Tony Phelan’s eight-episode biopic on Miep Gies, which is set to premiere on National Geographic May 1st.  

This will be Neisen’s first baby and a third child for Schreiber who already has sons, Alexander ‘Sasha’ 16, and, Samuel ‘Kai,’ 15, with his former partner, actress Naomi Watts, 54.

Watts and Schreiber split in 2016 after 11 years together but have nurtured a famously strong relationship as co-parents ever since. 

It remains unclear when romance blossomed between the Spotlight star and Neisen. 

The pair were seen surfing together in the Hamptons in 2018 and had not long returned from a vacation together with his children in Costa Rica.

By the following winter, in 2019, Schreiber and Neisen were regularly seen walking their dog together in New York City where Schreiber lives.

Originally from Rapid City, South Dakota, the former pageant queen was an entrant in Miss USA 2012 as the reigning Miss South Dakota.

She allegedly entered Schreiber’s life as the occasional nanny to his children with Watts before their working relationship turned romantic. 

In addition to his work in A Small Light, Schreiber has a mystery role in Wes Anderson’s 1955 stargazer convention-set rom-com Asteroid City, which hits limited US theaters on June 16 before a wider release on June 23.

The Sláinte Irish Whiskey co-founder will next play Nobel Peace Prize winner Henry Kissinger in Guy Nattiv’s biopic on Golda Meir starring Oscar winner Helen Mirren, which hits US theaters on March 10.
