Robert Pattinson and fiancee FKA Twigs enjoyed a jog together in the Malibu Hills on Tuesday.

The couple worked up a sweat as they hit the coastal trails to the north-west of Los Angeles, along with their precious pooch.

Pattinson, 30, and Twigs, 29, both wore sunglasses for their workout in true celebrity fashion.

The former Twilight star donned a pair of knee-length navy blue Adidas shorts and a khaki green t-shirt.

He added red Adidas trainers and wore a black hat.

His girlfriend of two years opted for an all-black ensemble of sweatpants and a long-sleeved shirt along with athletic shoes.

Their terrier-type dog appeared to have been given a custom haircut with its fur shaved off most of its body leaving just a body-length strand of fur along its back.

The actor, who has been promoting his latest film The Lost City Of Z, got engaged to the singer, real name Tahliah Debrett Barnett, in April 2015.

They prefer to keep their relationship out of the spotlight as much as possible.

As a result, they rarely speak about their romance, although Twigs has said the public attention it has garnered is '100 percent worth it'.
