Cowell has registered Lauren and his child at pricey Beverly Hills store Petit Tresor for high-end gifts.
Lauren is expected to give birth to the child in February.
"Simon wants to make sure it will be a day to remember for Lauren," dailystar.co.uk quoted a source as saying.
"He feels guilty she's had to deal with so much stress with his baby because of who he is," the source added.
