Los Angeles, Dec 15 (IANS): Reality TV star Kourtney Kardashian and her partner Scott Disick welcomed their second son Sunday. It's their third child together.

The newborn's birthday co-incidentally falls on the same day as the couple's five-year-old son Mason.

The couple is said to have decided that they want their son's name to be meaningful to them both. Though no name has been decided on yet, Kourtney and Scott know they want their son's name to "honour their fathers", reports hollywoodlife.com.

"They really want to honour their fathers and have talked very strongly on Jeffrey Robert. That would be the order the name would be presented," a source said.

"Scott really wants that more than Kourtney, she actually wants a more unique first name but may compromise and have Jeffrey as the middle name to make Scott happy as well," the source continued.

The couple also have daughter Penelope, 2, who now gets to have both a big and little brother.
