Liev Schreiber, 55, poses shirtless with bikini-clad wife Taylor Neisen, 31, as she shows off baby bump in selfie 

Liev Schreiber’s pregnant wife Taylor Neisen appeared on Instagram on Wednesday with cute new photos.

The 31-year-old mom-to-be and the 55-year-old actor – who are often spotted walking their pup in NYC – posed facing each other in one sweet selfie.

The former pageant queen snapped the photo with a yellow encased iPhone as they each smiled while looking at their reflections in a mirror.

Taylor, who married Liev in a secret ceremony in July, wore a black triangle bikini top, leaving her burgeoning belly exposed.

Her long, frosty blonde hair streamed out from underneath a vibrant orange trucker hat.

She added a horizontally-striped black and white skirt and the Ray Donovan star stood shirtless next to her.

The Hollywood fixture showed off his toned arms, chiseled chest, and fit abdomen in a pair of black and white striped trunks.

Above the image, which was shared in Taylor’s Instagram Stories, she wrote, ‘mom + dad.’

And on the grid of her social media profile, the beauty shared a precious black and white closeup shot of her bare belly.

She wore drawstring sweatpants that were situated underneath her bump, and the paw of their dog rested beneath her belly-button.

She wrote in a caption to her modest 6,000 followers, ‘BFFs.’

A source exclusively told DailyMail.com that the couple exchanged vows during a low-key ceremony attended by only four guests.

Two of them were Liev’s kids Alexander ‘Sasha,’ 16, and Samuel ‘Kai,’ 15, who he shares with ex Naomi Watts.

Also in attendance was author Jonathan Safran Foer, who officiated the wedding, and his wife.

‘They didn’t want a big fuss because Taylor is ready to give birth, but they wanted to bring the baby into the world as husband and wife,’ the insider dished.

The nuptials took place in the yard of the twosome’s sprawling, oceanfront Montauk abode – the home he once shared with Naomi, 54.

The former couple bought the 3,500-square-foot, four-bedroom, four-and-a-half-bathroom house together in 2016 for $5.4 million, but split just months later after 11 years together.
