Kylie Jenner is still keeping her son's real name a secret.

She revealed on the season 2 finale of "The Kardashians" that while she has chosen a new name for her 9-month-old son, the official name is still Wolf on the birth certificate.

“My son's name is still Wolf. I'll let you know when I change it," she told the camera, before teasing, "Maybe I'll tell you in Season 3."

Jenner has previously spoken about the pressure she felt at the hospital to name her son Wolf.

"We really didn't have a name," she said a few months ago. "We thought we'd know the name when we saw it, and we didn't."

Kylie also admitted she felt overwhelmed when it came time to sign the birth certificate, noting that her son needed some kind of identification or else he would be registered without a name or Social Security number.

In addition to hiding his name, Kylie has also kept the boy's identity a secret by not yet revealing his face on social networks.

In addition to their son, Kylie and Travis Scott have a 4-year-old daughter, Stormi.
