Drake's Son Bursts into Tears on Stage as Dad Accepts Artist of the Decade Award

Drake's 3-year-old son clearly has dad's knack for big moments -- he made an unforgettable night at the Billboard Music Awards even more memorable by getting emotional on stage.

The hip-hop star cemented his spot as a legend Sunday night as he was named Artist of the Decade, and his little boy, Adonis, took the stage with him to accept the award ... to give it an adorable boost.

As Drake spoke to the celeb-stacked crowd at the Microsoft Theater in L.A. about dedication to his music and using his fear to fuel improvement, his son hugged his legs pretty tight.

But, as Champagne Papi was closing his speech, Adonis seemed to have had enough and started walking away ... only to get picked up by Drake and start crying as his father dedicated the award to him.

As we first told you ... Drake's mother, Sandi, was also in attendance to watch him win the huge award Sunday night, which previously went to Mariah Carey in the 1990s and Eminem in the 2000s.

Drake and friends celebrated his win at SoFi Stadium -- home of the L.A. Rams and Chargers -- after the show ... and there was a massive message on the big screen.
