Liev Schreiber, who plays Sabretooth in the movie X-Men: Origins Wolverine, was spotted vacationing with his two sons and girlfriend Taylor Neisen in Costa Rica.

The duo has been romantically linked since late last year and this vacation together, with Liev's children with his ex-wife Naomi Watts, establishes that they are serious. The former Miss South Dakota looked at ease with Liev's sons Sasha and Sam.

On Monday, in the sandy beaches of San Jose, Costa Rica, the 26-year-old flaunted her toned tummy and shapely back by donning a deep blue bikini. The swimwear has been identified as a Brazilian style suit by iconic Aussie brand Kiini, and it features the two-piece in its signature multi-color crochet pattern. 

Many have found the look familiar since there is a long list of celebrities who have rocked the luxury swimwear including Coleen Rooney, Ellie Goulding, Cara Delevingne, Abbey Clancy and Bella Hadid. The two-piece called the Kiini "Tuesday" crochet costs £260 and is available online.

However, the blonde and her much older beau, 50, splashed playfully in the shallows. The former beauty queen's bright blue and colorful crochet made her look unmissable. Her outfit, which left very little to the imagination looked even stunning paired with her wet golden tresses swept back.

The family was accompanied by few of Liev's friends and the actor was seen going bodyboarding with his boys and enjoying the Central American weather. However, the Ray Donovan star appeared to have forgotten to apply a generous dose of sunscreen. His skin appeared to turn burnt red along his shoulders and arms. The blonde beauty held on to her man by putting her hands on his arm, while he showed off his muscular torso in a pair of black swim trunks.
