The singer joined Stevie Wonder and other mourners in Los Angeles to pay tribute to Etta James.
Before performing, Aguilera said: "It is an amazing honour for me to have been welcomed here today, invited here to pay tribute to the great Miss Etta James. I've since I've been able to tour, I've gone round the whole wide world and I would tell people that Miss Etta James was my favourite singer."
She added: "It's very emotional for me to sing today, as this has meant so much to me. All my life, I've aspired to sing like Etta James, to be like her, of all the singers I've ever heard, she was the one who cut right to my soul."
The 'At Last' singer passed away on Friday (January 20) following an ongoing battle with leukaemia since 2010.
Following the singer's passing Beyonce, who portrayed the 'At Last' singer in 2008 film Cadillac Records - posted her own message on her website:
"This is a huge loss. Etta James was one of the greatest vocalists of our time," she wrote. "I am so fortunate to have met such a queen. Her musical contributions will last a lifetime.
"Playing Etta James taught me so much about myself, and singing her music inspired me to be a stronger artist. When she effortlessly opened her mouth, you could hear her pain and triumph.
"Her deeply emotional way of delivering a song told her story with no filter. She was fearless, and had guts. She will be missed."
