Jessie J is haunted by the memory of meeting superstar singer Whitney Houston just a day before she died in a hotel bath tub.
The pop star was to perform along with late star Whitney at Clive Davis' annual pre-Grammy Awards party in Los Angeles and the pair were introduced at rehearsals by Whitney's daughter Bobbi Kristina.
Speaking to BBC Radio 1's Newsbeat, Jessie said: "(That day was) probably the most emotional day of my career... She (Bobbi Kristina) was like, 'My mum is here and wants to meet you'... Whitney was one of my huge inspirations. I've always spoken about her. She made proud to have a powerful voice."
Price Tag singer Jessie was shocked to hear news of Whitney's death at the Beverly Hilton hotel - the location where Clive Davis' party took place.
The star admitted she found her performance at the party difficult as she was singing in front of an audience of her heroes.
She added: "I had to really bring myself together and go, 'You can do it Jess'... In the audience were people that I've listened to and been inspirations. It wasn't easy... I was very proud to be representing the UK on such a kind of memorable night. Whitney Houston is someone that will never be forgotten and her music will live on forever."
