LOS ANGELES — Fans are mourning Nipsey Hussle at a public memorial held at the Staples Center in Los Angeles.

The Nipsey Hussle Celebration of Life ceremony started at 10 a.m. on Thursday. 

It was livestreamed on BET News' Facebook page.

The memorial  started with a reading from scripture and a slideshow of photos set to Frank Sinatra's "My Way."

Hussle was shot to death March 31 while standing outside his South Los Angeles clothing store, not far from where he grew up.

The 33-year-old Grammy-nominated rapper was a father of two and was engaged to actress Lauren London.

A letter from former president Barack Obama extolling the virtues of Nipsey Hussle has been read at the slain rapper's funeral.

The letter from Obama said he had never met the rapper, but had "heard his music through my daughters" and he later learned about Hussle's transformation and efforts to transform his South Los Angeles community.

He praised Hussle's vision, saying the rapper and community activist saw potential and hope in the Crenshaw neighborhood he grew up in and that lured him into a gang as a young man. Obama's letter states that Hussle "saw a community that even through its flaws taught him to always keep going."

The letter states Hussle's legacy is worth celebrating and Obama says he hopes Hussle's efforts inspire "more good work in Crenshaw and communities like it."

Eric R. Holder Jr., who is charged with killing Hussle, has pleaded not guilty.
