The gospel singer performed 'I Love the Lord, He Made Me Cry' in honour of Houston's life and legacy at the awards on Saturday (February 18). Adams has now said that she was honoured to perform one of Houston's favourite songs as part of the NAACPs tribute.
"It was so heartfelt," the star told ET Online. "First of all, she was an amazing person.
"It was very emotional, not because of Whitney, but because I know how she treated the song, and how much the love of the Lord was a part of her life."
The NCAAP Image Awards was broadcast just hours before a funeral for Houston was held at the New Hope Baptist Church in Newark, NJ.
Alicia Keys, Stevie Wonder, Kevin Costner and Marvin Winans were among the many mourners to share remembrances of Houston at the church where she first sang publicly.
Houston was then laid to rest in a private ceremony on Sunday (February 19) at the Fairview Cemetery in nearby Westfield, NJ.
