The 'X Factor' boss and Lauren have booked a delivery room in one of the most exclusive hospitals on the east coast of the US, so her mother, Carole Sandland, who lives in Florida, can be on standby and fly up to help her care for her first child with the British star, reported Femalefirst online.
"Lauren's mother will help her adjust to the newborn, as Simon will need to continue to travel to Los Angles and London regularly for work," a source said.
