Our hearts are melted! It's been nearly one month since Khloé Kardashian welcomed her baby daughter, True, with Tristan Thompson, and now, she's revealing the sweet nickname she uses for her little girl.

"I can’t believe my baby will be a month old tomorrow! Why does this make me happy and sad all at the same time. Thank you Jesus for my sweet peanut," the reality star wrote on Twitter. Aww, sweet peanut! She followed up with another tweet thanking fans. "I love you! Thank you for the sweet love to baby True. Night night babes."

On True's one-month birthday, KoKo is also gearing up for another big milestone — her first Mother's Day on Sunday, May 13! "I’ve always loved Mother’s Day and celebrating Kris Jenner,, MJ and my sisters — but this year will be even more special because now I’m a mommy, too!" she gushed on her app and website. "As of now, there aren’t any special plans (that I know of, LOL). I’m really enjoying spending quality time with True and loving just hibernating with her."

While we've yet to have been #blessed with a photo of Khloé's "sweet peanut," we do have an idea of what she looks like, thanks to her dad, Tristan, who just finally publicly acknowledged his baby girl's birth. "She has a full head of hair. She has green eyes," he revealed in a new interview. "This is the first girl Thompson, female Thompson, so it’s huge."

A source also previously revealed to Life & Style that True is so well-behaved. "The baby is such a good baby," the insider shared. "She doesn't cry, and everyone literally loves her."

Even though the couple is still dealing with the aftermath of Tristan's cheating scandal, which broke just days before they welcomed their first child together, they're still putting their baby girl first. "Tristan and Khloé both love [True] so much," a source told Life & Style. "Even though this bad thing is happening, they really are both in love with their child." Now all we need is a cute snapshot of True!
