La La's birthday message comes after she spoke to PEOPLE about Kiyan finding fame on social media after the teen garnered 782,000 Instagram followers.

"It makes me so proud," she told PEOPLE last month. "Since I do know it, I'm able to kind of talk him through it, make sure he understands."

"And he's so calm and humble and just a really great kid," she added of Kiyan's fame.

La La also revealed the few words of advice she has given her son when it comes to navigating stardom. "Don't listen to negative comments. Just do what makes you happy," she continued to PEOPLE.

"Just quiet the outside noise. I always tell him, 'Quiet the outside noise. It's not important,' " she added.

The proud mom also spoke with PEOPLE in December about Kiyan, who is already a nationally ranked high school basketball champion.

"He's got almost a million followers!" she said of his social media following. "He's not addicted to posting or anything like that, but he loves to put up his highlights from games or his workout routines. It's important, especially now that he's starting to visit colleges. You want people to know what you're doing."
