At last night's Grammys, there was a bittersweet moment where the show paid tribute to those in the music industry who had passed away, known as the "In Memoriam" segment. However, a short video tribute highlighting several of those late individuals were not enough for some viewers.

Natalie Cole's family and supporters are outraged that the singer did not receive a "respectful" tribute at the award ceremony, despite other deceased musicians being given musical tributes. In an interview with Entertainment Tonight, Cole's sisters called the late songstress' tribute "forgettable" and "disrespectful."

"Sadly a forgettable tribute to Natalie Cole," Cole's sisters, Timolin and Casey, told ET award ceremony. "Words cannot express the outrage and utter disappointment at the disrespectful tribute, or lack thereof, to a legendary artist such as our sister."

Unlike David Bowie, Maurice White, B.B. King, Lionel Richie, and Glenn Frey, who were all celebrated with musical tributes during the show, the daughter of Nat King Cole didn't receive the same attention.

The 65-year-old, nine-time Grammy winner, who passed on New Year's Eve due to complications from ongoing health issues, was only mentioned during the Memoriam segment of the awards ceremony.

"Here is a woman who has been in the business for four decades, had 21 Grammy nominations and won nine Grammys. She deserves more than a minute-and-a-half tribute," Cole's son, Robert Adam Yancy, told ET. "It was shameless the way they minimized her legacy. We will find solace in her legacy as well as her endless fans around the world."

Social media immediately erupted after the "In Memoriam," with fans and celebrities like Holly Robinson and "Empire" star Jussie Smollett weighing in on the Cole Grammy controversy.

"Natalie Cole... 9 Grammys and only gets a photo in remembrance montage. David Bowie...1 Grammy and he received a 7-minute tribute," Chris Witherspoon, CNN correspondent, wrote on Twitter.

Robinson wrote on Twitter, "We lost so many greats but Natalie Cole 1st African American to win Best New Artist deserves a tribute."

Smollett, 32, posted a black-and-white photo of Cole Tuesday and expressed his feelings towards the show's decision not to give the late "This Will Be (An Everlasting Love)" singer a proper tribute.

"For all you gave, you should have been acknowledged and honored in the correct way by your musical family and peers," he shared. "Shame on those who thought otherwise. It takes nothing away from anyone else's brilliance. We will remember, honor, respect and love you always Queen #NatalieCole. Only love."
