Despite what the public may have thought up until now, it’ll be a girl for Khloé Kardashian and Tristan Thompson.

The reality star revealed the news on Sunday’s season finale of Keeping Up with the KardashiansKhloé’s doctor told her sister, Kylie Jenner (who welcomed her first child, daughter Stormi, on Feb. 1), the sex of the baby, and she delivered the happy news to Khloé, who was visiting San Francisco with Kim Kardashian West (who welcomed her third child, daughter Chicago, via a surrogate on Jan. 15) and Kourtney Kardashian.

“I’m really hoping Kylie’s lying,” she said on KUWTK, admitting she’d been hoping for a baby boy.

But on Sunday, she clarified on Twitter that she’s thrilled to become the mother to a little girl.

“God gives us what we need! His timing is never wrong! my hormones were IN RARE FORM for that news,” she tweeted. “I am now so excited my daughter will have forever best friends with Chicago and Stormi!! God is great!!! Thank you Lord for our princess.”

Earlier in the episode, Khloé told her sisters she was “pretty much convinced” she was carrying a boy. “I have such anxiety and nerves to find out what I’m having,” she told the camera.

Kylie, 20, also commissioned a gender reveal cake for the big moment.
