With her astonishingly youthful looks, it is hard to believe she celebrated her 48th birthday last week.

And Julia Roberts showed off her incredibly shapely legs as she took her dog for a walk with a pal in Malibu, California, on Sunday. 

The Pretty Woman star wore a tiny pair of denim hotpants with an over-sized striped jumper while she enjoyed her leisurely stroll.

Walking the dog: Julia Roberts showed off her incredibly shapely legs as she took her dog for a walk with a pal in Malibu, California on Sunday

Julia showed off her incredible legs in her Daisy Duke-style shorts which she paired with khaki-coloured plimsolls. 

Giving the ensemble a sailor vibe, she wore a chic cream jumper which boasted three thick navy stripes around her torso and bust. 

The Oscar-winning actress paired the low-key look with Ray Ban aviator sunglasses, which gave a young trendy feel to the ensemble.

Julia's blonde tresses billowed in the wind as she wore them in loose, natural waves which fell from a centre-parting. 

Although her face was shielded by her sunglasses, Julia appeared to go make-up free for her casual walk, where her pal held on to the cute pup while she strode ahead. 

Ensuring she stayed hydrated in the Californian heat, Julia carried a water bottle as she embarked on her stroll.

Julia has clearly been loving the great outdoors, as just a day before her dog walking jaunt, she was spotted at her sons Finn, 11, and eight-year-old Henry's soccer match, also in Malibu.

She was joined by the boys' father and her husband of over a decade, cameraman Daniel Moder.

The loved-up duo, who are also parents to twins Finn and Hazel, 11, were packing on the PDA at the game as they became embroiled in a passionate kiss for all to see.
