A platinum band on Irish songwriter Johnny McDaid's ring finger has sparked rumours that he may have secretly married his ladylove actress Courteney Cox.

The two were spotted hand-in-hand, smiling and chatting animatedly during a romantic stroll here Sunday, reports dailymail.co.uk.

The 50-year-old actress sported a chic look with black skinny jeans teamed up with black suede ankle boots and a cosy beige ribbed knit.

The 38-year-old musician looked casual in black jeans, brown boots and a black T-shirt layered under a zipped-up thin black hooded sweater and matching leather jacket.

McDaid kept his left hand firmly in his pocket for the majority of the outing. However, he gave a couple of brief glimpses of the band.

At one point during their stroll, the couple stopped on the sidewalk for an affectionate embrace.

In June 2014, the couple had taken to Twitter to announce their engagement after dating for six months.
