Lauren London is speaking out for the first time after the devastating loss of her longtime partner, Nipsey Hussle.

The actress took to Instagram Tuesday night to share a series of intimate photos of their family. "I am completely lost. I've lost my best friend," she said. "My sanctuary. My protector. My soul.... I'm lost without you. We are lost without you babe. I have no words."

The heartbreaking tribute also showcased photos of the couple's 2-year-old son, Kross, whom they shielded from social media.

Tributes to the Grammy-nominated emcee and prayers for his family have been posted by a slew of notable names, including Beyoncé, Rihanna, Drake, LeBron James, Ava DuVernay, and Los Angeles Mayor Eric Garcetti.

The entertainer and entrepreneur was gunned down on Sunday afternoon in the parking lot of his clothing store, The Marathon, in the South Central Los Angeles community he called home. Eric Holder, 29, has been arrested for allegedly firing the shots that killed the rapper and injured two other men.
