According to E!, a source said that both Natalie and Gregory were found dead in their Las Vegas condo on Wednesday, May 13. "Greg's cousin woke up and noticed that Greg's car was still at the house. He was worried because Greg was to be in LA. His cousin went to check on him and found them," the source revealed.

The actor leaves behind his 10-year-old daughter, Alaya.

The source says that prior to his death Gregory was "really focused and handling a lot of business." And,  despite moving to Las Vegas to help his mother, the source revealed that Gregory "would commute to LA for acting jobs and to see his daughter."

His girlfriend Natalie was just twenty-seven-years-old.

In a statement shared to a GoFundMe, her family described her as being a "loving daughter, niece, sister, cousin, and friend. "Natalie had so much life to live [and] we are saddened that her life was cut short. Natalie leaves behind her one and only baby boy Egypt, her father, two brothers, and one sister, and a host of family and friends who love her dearly."

She penned an emotional tribute to her son yesterday.

"I'm sick without you. I'm torn, I'm lost. I'm in pain."

"I'd text you or call you when I was broken or worried about something, and you'd tell me, Ma, I got you, we'll get thru this together. Boy. Why did you leave me."

She continued:

"With you, the last time I saw you on Monday, May 11, 2020, I went to your house to eat leftovers from Mother's day, we watched a Dave Chappelle show and you walked me to my car, hugged me, kissed me on my cheek and told me that you love me and to call you when I got home."

Her post is utterly heart wrenching.

"That was it. Never another hug, kiss or to hear those words, I love you again. I'm broken. I love you Greggy, my Hunny."
