Liev Schreiber and ‘nanny’ Taylor Neisen vacation in Costa Rica

Liev your worries behind. “Ray Donovan” star Liev Schreiber is vacationing with his sons Sasha, 10, and Kai, 9, as well as his “friend” Taylor Neisen in sunny Costa Rica.

All together now! The pair looked like they were getting along swimmingly Monday while spotted vacationing on the beaches of San Jose, Costa Rica with Liev’s sons Sasha and Sam

We first reported in October that Schreiber, 50, and Neisen, 26, a former Miss South Dakota, were an item. Our sources also told us that Schreiber had been telling his pals that the stunning Neisen was “the nanny.”

Our insiders scoffed at that suggestion, noting that Neisen comes from an extremely wealthy family.

Schreiber’s rep at Slate PR assured us then that the pair “are friends and she sometimes helps out with the kids — they are not dating.”

Asked if the two were still just friends on Tuesday — after TMZ, Extra and JustJared.com identified Neisen as Schreiber’s “girlfriend” upon seeing brand-new photos of them together on a beach — Schreiber’s PR insisted: “They are friends. There is nothing to confirm or deny.”

It’s possible that Neisen’s nanny gig comes with perks. It could also be that going public with the relationship initially presented technical complications for Schreiber.

Schreiber and actress Naomi Watts, the mother of his kids, ended their 11-year relationship in September 2016. According to our sources, they struck a deal to keep their private lives out of the press for a year. In recent months, they’ve both been spotted out and about with other people in social situations.

Watts was photographed holding hands with her “Gypsy” co-star Billy Crudup at last week’s BAFTA Awards in London. Schreiber and Neisen have been seen in New York on multiple occasions — sometimes with no kids in sight.

Schreiber, who plays a crisis manager in Showtime’s “Ray Donovan,” spent the first five years of the show filming in L.A. The show’s upcoming sixth season will be set in New York.
