As Radar previously reported, Gregg lost his years-long battle with colon cancer this past Wednesday. He was 66.
Taking to Instagram on Friday, the 53-year-old Linnethia Lounge owner posted a video showing her late husband sweetly whispering to her, "You're the one for me," while she had her arms wrapped around him.
The duo seemed to be enjoying their time together while listening to live music at an event. The reality star captioned the heartbreaking post, "I just can't," along with a red heart and broken heart emoji.
Messages from friends and fans poured in to show support for the Leakes family, including comments from fellow RHOA alum Phaedra Parks and Real Housewives of New York star Luann de Lesseps.
Phaedra said, "Love never dies," accompanied by hearts, praying hands and a kiss emoji, while Luann wrote, "Beautiful sending you love & prayers so sorry for your loss Nene."
The Glee actress broke her silence on her husband's death on Thursday with an emotional video of them dancing together. NeNe was seen smiling uncontrollably as she serenaded Gregg, who looked just as happy as she did.
It seems that her former RHOA co-star, Porsha Williams, was the one filming the precious moment because her voice could be heard cheering them on in the background.
The TV personality has been showered with endless support from family members, friends and fans since the news of Gregg's passing broke.
As we exclusively reported, Linnethia Lounge in Duluth, Georgia, is gearing up to host a three-day event in his honor.
Staff members told us they would be pulling out all the stops to celebrate his life and that the celebration would go all weekend long, starting on Friday and ending on Sunday.
Employees told us they had been receiving calls endlessly from people offering their condolences to the reality star and her family.
Several days ago, NeNe informed patrons at her lounge that her husband was losing his cancer battle.
She made the heartbreaking announcement that his passing was imminent after a customer accused her of being rude for not wishing them a happy birthday.
NeNe responded by asking the public to have more compassion toward her, explaining that "sometimes, you don't know what people are dealing with."
"My husband is transitioning to the other side," she revealed to the crowd, later sharing a captionless Instagram post that read, "Broken."
Days later, Gregg was pronounced dead.
"After a long battle with cancer, Gregg Leakes has passed away peacefully in his home surrounded by all of his children, very close loved ones and wife NeNe Leakes," a spokesperson for the family said in a statement. "We ask that you pray for peace and strength over their family & allow them to mourn in private during this very, very difficult time."
