A fourth little West is on the way, and Kim Kardashian is already “Googling” baby names.

“I was Googling Armenian boys’ names last night, and I couldn’t really find anything,” the 38-year-old reality star told Jimmy Kimmel on Monday’s Jimmy Kimmel Live! in Las Vegas, joined by her two sisters, Khloé and Kourtney Kardashian.

And although the Armenian boys’ names didn’t stick, she revealed that she liked the idea of naming her new baby after her brother, Rob Kardashian.

“I was truthfully thinking about just naming him Rob, after my brother, Rob,” she admitted on the show. “But then it’s kind of like North, Saint, Chicago, Rob. It doesn’t really go, but I was really feeling that. And my brother approved it, so that’s like our one kind of name.”

But it may take a few days after the baby is born for Kardashian West to be sure of the new little one’s moniker. The sister trio revealed that the famous family takes their time trying out names after the baby is born to help them decide.

We’re trying to figure out what the baby looks like,” Kardashian West explained to Kimmel. “I usually go about three or four days nameless until I feel like it really connects with the baby.”

Kourtney also used this method when it came to naming her son Reign, 4, saying she tried out a different name on different days.

“One day, Reign, his name was Preston for one full day,” she recalled. “I was like, ‘I know in my soul his name is Reign,’ and Scott [Disick] didn’t believe me.”

Kardashian West and her husband, Kanye West — who are already parents to Chicago, 14 months, Saint, 3, and North, 5 — are expecting their fourth child via surrogate.

An insider previously told PEOPLE that the couple had already begun talking about adding a fourth child to the family when Chicago was just a few days old.
