In honor of his 45th birthday, Notorious B.I.G's son stepped out on stage with Diddy at the 2017 Billboard Music Awards.

Looking just like his famous rapper dad, the duo came together to premiere a trailer for a documentary about Biggie's life and unexpected death.

March 9 marked the 20th anniversary of The Notorious B.I.G.’s death. And though the rapper left this world far too soon at the age of 24, the two kids he left behind — T’yanna, 23, and Christopher Jr., 20 — are thriving!

Biggie, whose real name is Christopher George Latore Wallace, was killed in a drive-by shooting in 1997 when his children were just three-years-old and four-months-old. And though they didn’t know their dad for long, the duo has kept his legacy alive through their work.

T’yanna is the owner and CEO of Notoriouss Clothing, while Christopher followed in his dad’s footsteps by becoming an entertainer. He appeared in the 2016 film Kicks and is planning on releasing an album with his rap group CJ & Jahad later this year.

“The Wallace name is big, I’m not gonna lie… I try to just continue the legacy. That’s why I started my clothing line dedicated to him,” T’yanna said in an interview last June. “I’m not into music, I don’t rap or anything, so I was like, let me do something that I love dedicated to him.”

“My dad’s story on just how he came from Brooklyn to the top — its just, plain and simple, dreams come true,” she added in a separate interview.
