Jeremy, 47, looked content and comfortable as he enjoyed the company of his female companion.

Piven first of all enjoyed a leisurely drink as he sat outside Daylesford Organic Market soaking up the atmosphere.

Jeremy was seen puffing away on a large cigar as he was lost in writing some notes down while sipping on a cup of coffee.

The mystery woman then joined him and they were seen strolling off together looking happy and relaxed.

The Hollywood star dressed fairly smart for the outing as he stepped out in a pair of trousers with brown shoes.

He completed his look with a co-ordinating brown jacket and black T-shirt underneath while he wore specs on his face.

His lady friend also went for a smilar smart casual ensemble in skinny jeans and suede brown boots which perfectly matched Piven's.

She kept warm in a light pink cardigan as she carried her bags over both arms.

And whatever she had to say obviously interested Jeremy who smiled and giggled as they stopped and spoke to each other.
