"I feel grateful, proud and relieved — in that order! It's a surreal feeling to be done with something that was such a huge part of my life. Now, like every other graduate, I'm on to the next chapter," she said.

Aoki continued, "I'm so thankful for the village of people that spurred me along and helped keep me focused. My mom, my sister, my little brothers back at home. It took a whole tribe, trust me!"

Her mom also had a few words to share about her daughter's graduation, telling PEOPLE, "This has been a banner season for our family. Both my daughters graduating the same year — wow! I can't begin to express how proud I am of them. They're both such brainy beauties! And they're all mine!"

Kimora continued, "I want Aoki Lee to keep the same energy and passion she's shown her entire life. It's nice to have a Harvard grad in the family, but it might be nice to have an attorney, too. I've promised myself I'll wait at least a week before I start gently nudging her in that direction, though."
