This comes one week after her boyfriend and baby daddy Tristan Thompson was reported by DailyMail.com to be cheating on the siren with a club employee by the name of Lani Blair.
In her Instagram post, which showed a room full of pink flowers and balloons, she wrote: 'Our little girl, True Thompson, has completely stolen our hearts and we are overwhelmed with LOVE.'
The Keeping Up With The Kardashians matriarch has been supporting her daughter, who gave birth to a baby girl just two days after the DailyMail.com unmasked Thompson as a love rat.
Khloe welcomed her little girl at the Cleveland Clinic in Ohio on Thursday.
A source told Entertainment Tonight: 'Khloe needs her mom more than ever now.
Everyone has always seen Khloe as the strongest sister, but in light of the new baby and the timing of Tristan's cheating scandal, having her mom by her side has been so essential in keeping her spirits high.
'Khloe and Kris are spending true bonding time with the new baby.
'Kris is teaching Khloe the ropes when it comes to breastfeeding. People always hear of the drama that goes on in the Kardashian family but Khloe and her mother have spent some wonderful moments together despite the recent news.'
Thompson is believed to have spent time with at least five different women in the past several months, including Blair, and women named Stephanie, Maria and Tania.
Despite the devastating timing of the reports, Khloe's family are rallying around her.
