Holding a large container of water over his head, he emptied the entire contents over his face and rippling torso.

During the outing, the 45-year-old actor was joined by a male pal and his youngest son Samuel whom he shares with Naomi.

The tiny tot was seen running around the sand in a Batman T-shirt and rolled up trousers throughout the day.

Meanwhile, Liev was showing off his surfing skills in the water, expertly catching numerous waves throughout the day.

Father and son were enjoying some down time while Liev's other half Naomi was travelling back from Paris after attending Fashion Week.

On Wednesday, The Oscar-winning star attended the Louis Vuitton show in the French capital wearing a stunning all-white ensemble.

The 44-year-old actress showed off her incredibly long legs in a white short-sleeved minidress and matching coat as she posed up ahead of the Fall/Winter 2013 show.

Adding a splash of colour to her ensemble, Naomi opted for a patent pale green handbag and a pair of black heels.

Mother-of-two Naomi wore her blonde hair, which has only recently been cut from shoulder-length into a bob, in curls, and smiled widely for the waiting photographers outside the event.

Naomi is a lover of sleek and slimline designs, so would no doubt have been a fan.

Designer Marc Jacobs explained his autumn collection for the brand as the women having 'an attitude of getting dressed up only to find the most glamorous destination is one's own hotel room.'

Casual arrival: Naomi arrived back in Los Angeles on Friday
