Christina Aguilera says her duet with a hologram of Whitney Houston will go head in the future.

She told Access Hollywood: "I was honoured that the Houston family asked me to perform a duet with the legendary Whitney Houston. Sadly, the technology could not meet up to the talent that Whitney possessed.

"I do know in time the performance the fans and I have been hoping for will come to life."

Christina's comments came after Pat Houston, who is the ex ecutor of Whitney's estate, said they decided to cancel the performance because the technology was not perfect.

She said: "We are so appreciative of the opportunity for the Whitney Houston hologram to appear on NBC's 'The Voice' with a talent pairing as extraordinary as Christina Aguilera and Whitney Houston. We were looking to deliver a ground breaking duet performance for the fans of both artists.

"Holograms are new technology that take time to perfect, and we believe with artists of this iconic calibre, it must be perfect. Whitney's legacy and her devoted fans deserve perfection. After closely viewing the performance, we have decided the hologram was not ready to air. We have much respect and admiration for Christina, and she was absolutely flawless."

Meanwhile, the 35-year-old singer - who sits on the show's judging panel alongside Blake Shelton, Adam Levine and Pharrell Williams - previously teased there were some "very exciting" things planned for the future.

Last year Hologram USA showcased plans to take the virtual likeness of the 'I Will Always Love You' singer on a world tour. Whilst no details have been announced as of yet, the move was approved by Pat.

She said in a statement at the time: "It's a great opportunity for her fans to see a reinvention of one of the most celebrated female artists in history and to continue a legacy of performances that will not be forgotten in years to come."
