Reality show star Kourtney Kardashian and her husband Scott Disick welcomed a second baby boy on 14 December, the same day as their eldest son Mason's fifth birthday.
Though the celebrity couple has not revealed the name of their third child, several rumours are doing rounds that the newborn will be named after Disick's father Jeffrey Robert.
"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. Scott really wants that more than Kourtney," a source close to the stars told Hollywood Life.
The person also informed that Kourtney "wants a more unique name" for her third child but the celeb might compromise and "have Jeffrey as the middle name to make Scott happy as well".
However, the fans of "Keeping up with the Kardashian" star are eagerly waiting to know the name of the new member of the Kardashian family.
Meanwhile, Mason celebrated his birthday with little sister Penelope, cousin North West, aunts Kim Kardashian, Khloé Kardashian and Kendall Jenner.
"Happy Birthday to the lego master Mason!!! You are so big I can't take it! You are my everything! I love you so much!" Kim twitted.
Kourtney also wished her eldest son through Instagram, she wrote, "Happy birthday to the coolest little boy in the entire world. You teach me so much every single day and changed my universe the second I met you. You have taught me what life is all about and I am truly blessed and honoured to be your mommy."
