Drake and Snoop Dogg paid tribute to fellow rapper Drakeo the Ruler, who was fatally stabbed at a concert in Los Angeles on Saturday.

A man stabbed Drakeo the Ruler during an altercation at the "Once Upon A Time in LA" event held Saturday at Banc of California and Exposition Park in Los Angeles. The rapper was 28 years old.

The event, in which Drake and Dogg were also scheduled to perform, was canceled after the incident. Drake took to Instagram Stories on Sunday to share a photo of Drakeo, whose real name was Darrell Caldwell.

Drake wrote, "Nah man this s--t isn't right for real wtf are we doing. Always picked my spirit up with your energy RIP Drakeo."

A Twitter user shared a screenshot of the Instagram post, along with a photo of Drake and Drakeo together.

Dogg took to Twitter on Sunday to share a heartfelt message.

"I'm saddened by the events that took place last night at the Once Upon a Time in La Festival," the 50-year-old wrote. "My condolences go out to the family and loved ones of Drakeo the Ruler."

Dogg further wrote that he did not support "anything negative" and was at the event to spread positive vibes to the city.

"Last night I was in my dressing room when I was informed about the incident and chose to immediately leave the festival grounds," he added. "My prayers go out to everyone affected by the tragedy. Please take care, love one another and stay safe ya'll."

He concluded the post by adding, "I'm praying for peace in hip hop."

Many users asked where the security was when the incident took place and how someone with a knife was able to enter the venue.

Another user compared the incident to Travis Scott's Astroworld tragedy. Ten people died and hundreds were injured in a stampede during Scott's concert in Houston in November.

Drakeo the Ruler struggled with legal battles throughout his music career. He released his first studio album, "The Truth Hurts," in February. He was featured in a music video, "Risky," in April.
