Khloé Kardashian Shares Cute Photo of Daughter True After Welcoming Baby Boy: 'Happy Sweet Girl'

Khloé Kardashian is showing her daughter some love after welcoming a new addition to the family.

Over the weekend, the Good American co-founder, 38, gave her 4-year-old True a special shout-out on Instagram, calling the little one her "happy sweet girl."

In the cute photo, True sits on a countertop and smiles while posing in front of a pink and purple floral display in the shape of a cat. True, whom Kardashian shares with ex Tristan Thompson, wears a pair of pink tie-dye pants, a floral top with pink buttons and her hair in pigtails.

The tribute to True came two days after a rep for Kardashian told PEOPLE that she and Thompson –– who split in January –– welcomed their second baby together, a son, via surrogate.
