Australian Prime Minister Malcolm Turnbull with granddaughter Isla, who will soon have a sibling.
Prime Minister Malcolm Turnbull will become a grandfather for the fourth time in April - the same month Barnaby Joyce's fifth child is due.
Speaking at Chinese New Year celebrations in Melbourne on Sunday, Mr Turnbull said his son's wife was expecting a second child.
"Our Singapore family, our son Alex and his wife Yvonne are not able to be here with their daughter Isla because she is having our fourth grandchild in April, so we're very excited about that," Mr Turnbull told the crowd.
