Singer Jessie J has paid tribute to her hero Whitney Houston at the pre Grammy Awards show last night, where she dedicated her song Who You Are in her memory. The party was hosted by Houston's former mentor Clive Davis and the tragic singer was scheduled to attend.

The singer, real name Jessica Cornish tweeted on her official page: 'I think today was the most emotional day of my career... I am lost for words and so overwhelmed. Whitney I sing because of you and will continue to do so in your honour always and forever. X. Today is a surreal and memorable day. Still sinking in... We are all so blessed we was alive in the lifetime of Whitney and all were able to look up to her musically and spiritually. No better music inspiration than her voice, energy and music. #grammys.'

In January 2012, Cornish spoke to radio station Capital FM about the background of her recent number one hit, which was inspired by Houston. 'Me, Claude [Kelly] and [Dr.] Luke sat and listened to Whitney Houston in the studio, and Prince. I was like, 'I want to write my version of that in this day and age.""[We] wanted to do something up-tempo, fun, everyone can sing along to it, every age can dance to it. It's such a happy song, it makes me smile.'

Before she broke through, Cornish uploaded a video of herself covering Houston's I Have Nothing, which was originally released in 1993 and taken from the soundtrack to The Bodyguard, which Houston starred in.
