The reality TV star was flattered to find Dunham had recently used one of Khloe's quotes from her app, which featured a photo of the "Keeping Up With the Kardashians" star on her social media page.
"True thanks for this necessary reminder @khloekardashian," Lena captioned her Instagram post, adding, "(yes I bought the app. And I learn things from it every day)."
Now Khloe has responded to the complimentary post with a full blog entry, titled 4 Ways Lena Dunham Is Pretty Much My Soul Sister.
"I love what Lena stands for: She is honest, real and thoughtful and brings all of that to her fans with her super inspiring site, Lenny Letter. I connect with her message so much," she continued.
