Joe Swash and Stacey Solomon proved their love was as fun as ever as they enjoyed a romantic evening walk on Monday evening.The ex-EastEnders star filmed his girlfriend, 30, from behind as she carried their one year old son Rex in a baby sling while walking through a field, jokingly ogling her bum and catcalling her. While walking ahead of him in a pair of bright pink dungarees a strap swung loose from the sling Stacey was wearing, which Joe, 38, couldn't resist saying looked like a tail.
