Artists including Drake, Rihanna and J Cole have paid tribute to Los Angeles rapper, Nipsey Hussle
The 33-year-old, who was gunned down outside his clothing shop in Los Angeles was described as "a man of respect and a don" by Drake.
Rihanna wrote on Twitter: "This doesn't make any sense! My spirit is shaken by this!"
Two other people were injured in the shooting outside Marathon Clothing in south Los Angeles.
Lt Chris Ramierez of the Los Angeles Police Department told media at the scene of the shooting that they were looking for a black male suspect.
Nipsey Hussle's debut album Victory Lap received a nomination for best rap album at this year's Grammy Awards, where he was nominated against Cardi B, Mac Miller, Pusha T and Travis Scott.
Writing on Instagram, Pusha called him a "rare breed" adding: "Sad to see you go Nip, I'm only finding peace in knowing you are blessed... I was honored to share in such an amazing year with you musically.
"I would gauge everyone's music credibility based on if they mentioned you."
Drake, who won a Grammy on the same night and recorded the 2009 track Killer Nipsey Hussle, also took to Instagram to pay tribute.
"My whole energy is just at a low right now hearing this," he wrote. "We just linked for the first time in years and said we were gonna do a new song this summer cause it had been too long. "
"You were having the best run and I was so happy watching from distance fam nobody ever talks down on your name you were a real one to your people and to the rest of us."
Other to pay tribute included rapper J. Cole and maker and artist Pharrell Williams.
