Conor McGregor puts his bulging muscles on display as he joins fiancée Dee Devlin and their children Conor Jr, five, Croia, three, and Rían, 13 months, in St Tropez

Conor McGregor showed off his muscles as he and fiancée Dee Devlin took their kids for a sunny stroll in St Tropez on Friday.

Conor, who snapped his left tibia in the first round of his last fight – the third of his trilogy with Dustin Poirier – in July last year, has posted an video on Instagram of a training session where he kicks a heavy bag with his formerly injured left leg.
