Kelly Osbourne is smaller than a size 6.

The media star - who has lost considerable weight since her split from model Luke Worrall- admits even a size 6 dress was too big for her on a recent outing at New York Fashion Week.

She told Closer magazine: "It was a UK size 6 but, incredibly, it was too big for me! I couldn't believe it - I thought was a size 6 for goodness sake! I had to be taped into the dress because it was falling down!"

The 25-year-old beauty enjoyed a number of shows in New York last week, noting her love for both Jeremy Scott and Marchesa.

Writing on twitter, she said: "The Jeremy Scott show was out of this world I sat next to Kanye West who might I just say is hilarious !!!

"Marchesa was the most beautiful collection I have ever seen in my life!(sic)"

However, her small figure has not improved her love life, and Kelly is concerned she is becoming fictional British character Bridget Jones.

She said: "Watching Bridget Jones and facing the harsh reality that i am her!!!! :( (sic)"
