Kourtney Kardashian and Scott Disick reportedly welcomed a baby boy into the world on their oldest son’s birthday, but the couple has not publicly commented on the alleged birth. While multiple news sources claimed the Kardashian-Disick brood now numbers five, none of their famous Kardashian-Jenner family members wished them well publicly.

One of the other facts that has some people doubting the child was born Sunday is that a name has not been revealed, nor other details. Since hip baby names are all the rage, many Kardashian fans are clamoring to know the infant’s moniker. As with Mason Dash, 5, and Penelope Scotland, 2, the new edition’s name will reportedly pay homage to his ancestors, a source told Hollywood Life.

Both Disick and Kardashian’s fathers are dead, and the couple wanted to honor them, a source told the news site exclusively. “They really want to honor their fathers and have talked very strongly on Jeffrey Robert,” the source said. “That would be the order the name would be presented.”

Celebrities are known to choose wacky names for their little ones, but Jeffrey Robert -- if that is indeed his name -- can reportedly thank his father for the traditional moniker. “Scott really wants that more than Kourtney,” the insider told Hollywood Life. “Kourtney actually wants a more unique first name.”

On the day when their little brother was allegedly born, Mason Dash and Penelope Scotland went to see Disney on Ice with aunt Kim Kardashian, Kanye West and cousin North West, 18 months, at the Staples Center in Los Angeles, Us Weekly reported. The reality star tweeted several pictures of their outing.

"Mason and Penelope had big bags of cotton candy," a source told the news site. "They seem like an adorable family."
