Khloé Kardashian Shares Rare Family Photo Featuring Her Baby Son and True

Khloé Kardashian still hasn't revealed her baby boy's name, but he's finally starting to make appearances on his mom's Instagram grid. On Sunday, the Good American founder shared a new photo of her son and 5-year-old daughter, True — both of whom she shares with her ex Tristan Thompson — on Instagram.

In the photo, Khloé sits holding her little boy and True on her lap. The baby is rocking a camouflage sweater and a fireman's hat over a white beanie. Meanwhile, True is grinning and wearing a black T-shirt. The photo appears to have been taken at Khloé's nephew Psalm West's birthday party. Kim Kardashian celebrated her youngest child's fourth birthday over the weekend with a firefighter-themed party.

Both Kim and Khloé posted numerous photos from the party on their Instagram Stories. In one story, Khloé revealed her baby's tiny firefighter jacket. While all of the other kids' jackets had their names on them, his simply read "T. Thompson."

The reality TV star captioned her post with three bear emojis, but she didn't appear to drop any hints about her son's name. In April, Khloé confirmed on an episode of "The Jennifer Hudson Show" that her son's name starts with the letter T and promised she would share it soon. "He's been named, but I've been waiting for the premiere of our show."

Season three of "The Kardashians" is set to premiere on Hulu later this month, but Khloé is a little scared her daughter will spill the beans ahead of time. "I didn't know it was going to be this far out. So now I'm just like, if my daughter outs me, I'm screwed."

The mom of two went on to add that she didn't have a name in mind for her son before he arrived. "He was delivered via surrogate, or the stork, I like to say, and at first, I did not know what I was going to name him," she explained. "I wanted to meet him and feel him out a little bit, and so at first, he didn't have a name."
