They recently grabbed some bonding time in New York City. And Scott Disick, 34, again spent quality father-son time with Mason, seven, the eldest of his three children with ex Kourtney Kardashian, on the beach in Miami on Saturday.

The reality TV star and his son were joined by Disick's friends for the weekend outing.

Scott dressed in a white T-shirt, navy shorts and went barefoot for the day at the beach.

The son, Mason matched Dad's casual attire, slipping into a gray T-shirt with the word 'GRIZZLY' emblazoned across the front and wearing shorts.

His dad wore tortoiseshell framed sunglasses for the outing and sipped on fresh coconut juice and the pair lounged on deck chairs. Not seen with the duo was the bearded 34-year-old's latest girlfriend, 19-year-old Sofia Richie.

A source told People that Richie, 19, has been a positive influence on Disick, 34, who has had a party boy reputation and well-documented struggles with alcohol abuse.

'She’s been great for him,' the insider said. 'She’s made a big impact on his life and he hasn’t partied at all since they met.'

Scott shares three young children with former girlfriend Kourtney and still appears on the family's reality show Keeping Up With The Kardashians.

In addition to Mason, he is dad to daughter Penelope, five, and son Reign, who is set to turn three years old on December 14.
