Whitney - who has battled an addiction to crack cocaine and whose divorce from Bobby Brown was made official earlier this year - flew in from New York for the event and had been in hiding at a London hotel to avoid ruining the surprise.
Arriving on the red carpet at around 11.15pm, she said: "I know it's been said before but I want to say it again - thank you for your support and, yes, I will always love you."
