Now, Pat Houston, executor of the estate, has issued the following statement exclusively to ET's Kevin Frazier.
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 caliber, it must be perfect. Whitney’s legacy and her devoted fans deserve perfection. After closely viewing the performance, we decided the hologram was not ready to air. We have much respect and appreciation for Christina, and she was absolutely flawless.
ET previously spoke with Aguilera about the planned performance, though she kept mum on the details.
"I am sworn to secrecy," she stressed during a backstage interview at The Voice on May 9. "I can't say anything, but I'm very excited about the finale. Very exciting things happening."
News of the planned hologram in the singer's likeness was first announced in September 2015.
"It's a great opportunity for her fans to see a reinvention of one the most celebrated female artists in history and to continue a legacy of performances that will not be forgotten in years to come," Pat Houston said in a statement at the time.
According to a press release, the hologram would then perform its own headlining show in 2016. The interactive show, created by FilmOn Studios, was said to be opening at "a major U.S. venue and tour the world," featuring a selection of Houston's biggest hits.
