"Whitney herself stated in 2001 that Christina Aguilera sang the best version of her song 'Run to You,'" the Estate of Whitney E. Houston said in a statement. "It is with great appreciation and honor that she is returning to participate on the American Music Awards for a special tribute honoring the 25th anniversary of The Bodyguard. Whitney said that Christina is without a doubt one of the best voices she enjoyed in this generation of music. From the Estate of Whitney E. Houston, we thank you with great joy!"
Meanwhile, the "Beautiful" singer also expressed how grateful she was to honor her idol.
“To be honoring THE one and only Whitney Houston is a blessing, and I am grateful to celebrate the spirit of her songs and legend that lives on. I feel eternally fortunate to have personally met her on and off the stage," Aguilera wrote in a statement. "My deep appreciation for her kindness to me while coming up in the business -- her graciousness, generosity, humanity and beauty -- lived up to everything I could have hoped for in meeting my idol and will forever be cherished in my memory of her.”
