Lauren London, actress and longtime girlfriend of slain rapper Nipsey Hussle, shared her feelings of being “completely lost” without him Monday.

Her Instagram post is the first time London has posted on social media since Hussle, whose real name is Ermias Joseph Asghedom, was shot and killed Sunday in front of his Los Angeles business, Marathon Clothing.

“I am completely lost

I’ve lost my best friend

My sanctuary

My protector

My soul....

I’m lost without you

We are lost without you babe

I have no words”

London posted her message just hours after police arrested Eric Holder, the man they believe killed the Grammy award-nominated lyricist, who was celebrated for his album "Victory Lap" just last year.

London and Hussle met in his clothing store. They were together five years and have a son, Kross Asghedom.

On March 28, GQ posted a video of London and Hussle taking its “Couples Quiz,” where the actress asked the rapper 30 questions about her and their relationship. Hussle answered 24 of the questions correctly.

Shaun King, Kimora Lee Simmons, Tia Mowry, Marlon Wayans and thousands of others offered support and prayers on the post. Since Hussle’s death, London has received an outpouring of support on social media.

In addition to Kross, the couple formed a tight-knit family with Emani Asghedom, Hussle's daughter from a previous relationship, and Cameron Carter, London's son with rapper Lil Wayne.
