Liev Schreiber had a family day this weekend.

The Ray Donovan actor took his longtime girlfriend, Taylor Neisen, and child Sasha, 14 - whom he shares with ex Naomi Watts - on a bike ride in the Hamptons neighborhood of Long Island in New York.

Also with the family was their dog, who was pulled along by its leash as Liev pedaled away.

His better half wore white dress and multicolored bucket hat. 

His 14-year-old child, Alexander (who goes by Sasha), wore a dark blue Dos Equis t-shirt, a yellow hat with a smiley face in the center and blue athletic shorts. 

The group rode together after eating a hearty breakfast.

The actor and the former Miss South Dakota have been dating for years now. 

The two were first linked in 2017 about a year after Schreiber ended his relationship with his longtime partner, and mother of his children, actress Watts. 

During their partnership, which lasted more than a decade, Schreiber and Watts had two children together. Alexander was born in 2007 and younger child Kai was born in 2008. 

During the couple's split, they released a statement regarding raising children together.

'It is with great love, respect, and friendship in our hearts that we look forward to raising our children together and exploring this new phase of our relationship.'

The Isle of Dogs actor and his current flame initially said they were not dating but just friends. 

Schreiber has also been busy professionally in recent years as well. While Ray Donovan was cancelled last year, Showtime announced in February that a movie for the show will come out in 2022. 

Schreiber also shot Across the River and Into the Trees during late 2020 and early 2021. Schreiber will play the lead role of Colonel Richard Cantwell. 

The film revolves around Schreiber's character seeking inner peace after being wounded physically and mentally in war. It is based on the Ernest Hemingway novel of the same name.
