The 36-year-old actress' former partner was shot dead in March 2019, but Lauren thinks it's important to set a good example for her kids by returning to work.
Lauren - who had four-year-old son Kross with Nipsey, as well as 11-year-old son Kameron with Lil Wayne - said, "We can't stop, you know? We do have a purpose, all of us, and it's important for my sons to see me moving forward with grief, not just curling up in a ball, because I curled up in a ball for a long time."
"But especially for my eldest son because he's just a little more aware ... But we will continue moving on as we had to, as he would want us to."
She told Entertainment Tonight, "We shot it in 2019 I believe - and forgive me, my memory doesn't serve me so well after grief and everything."
"Michael reached out to me as a friend and he was so unsure if I was even going to ever work again. And he was like, 'Look, I'm unsure if this is what you want to do, but I have to follow my intuition, I have to ask you if can you just read the script.' "
Lauren also admitted that Nipsey's death has changed how she approaches her career.
She said, "Moving forward in my life, I kind of don't want to do anything that I can't really truthfully contribute and I felt like I could truthfully contribute to this project."
