Kim Kardashian has accidentally revealed that she and husband Kanye West are going to proud parents of another daughter.

The reality star, who turned 37 last month, inadvertently let the baby's gender slip during Wednesday's (Nov. 15) episode of The Ellen DeGeneres Show. Kardashian is already a mother to two children; daughter North, 4, and son Saint, 1.

The KKW Beauty founder confirmed last month that she and her rapper husband are expecting their third child via surrogate. The expectant mother made the official announcement during an episode of Keeping Up with the Kardashians.

During an appearance on Ellen's show, Kardashian was asked about the lavish and beautiful cherry blossom-themed baby shower she hosted over the weekend at her Los Angeles residence. It was attended by sisters Kylie, Khloe, Kendall, mom Kris, Chrissy Teigen, Mario Menounos and celebrity hairstylist Jen Atkins among others.

Speaking as the host, the reality star had this to say about the pink-themed party: "People brought toys and gifts and she was opening them all up the next day and she (North) said, 'Mom, since baby sister's not here, I think I need all of her toys in my room and I'll play with them and just make sure they're all okay for baby sister.'"

When DeGeneres pointed out that Kardashian had just accidentally revealed the baby's gender, she realized her blunder and started laughing.

Kim K noted that North is super excited about the baby's arrival. As for her son, Saint, who turns two next month, Kardashian said she thinks he's too young to understand that he's going to have a new sibling soon, especially when she doesn't have the baby bump.

Kardashian admitted that she and the "Famous" hitmaker haven't even picked a name for the baby yet and are "freaking out" because of it.

"At the baby shower, I was like, "I just want everyone to write a name on a little tile and see if there is something that sticks,' We're freaking out, we have no name," she told the host.

A source confirmed to People in September that Kardashian and West are welcoming a baby girl and she's expected to arrive in January. "They are so excited about their future baby girl," the source said. "They can't wait to add a new addition to their family and are just so incredibly happy."
