Aw, this is so sweet!
Russell Simmons and Kimora Lee's daughters Ming and Aoki serenaded their poppa by sending him a adorable Happy Birthday video.
Kimora even makes an appearance at the end of the vid!
Even though Russell and Kimora are divorced, they've remained very close and have a wonderful relationship with each other and their daughters. How respectful!
