Conor McGregor took his growing family out to the beaches of the South of France this week ... and the UFC superstar was clearly excited for his baby on the way -- kissing his partner's tummy during the outing!!
The Notorious and Dee Devlin threw on their bathing suits and soaked up the sun during their getaway ... chowing down on some food, running in the water and taking selfies.
Conor also showed his love for his unborn fourth child ... rubbing all over Dee's stomach and hugging her.
