Whitney HoustonFiling for divorce seems to suit Whitney Houston: she stunned onlookers with her glamorous appearance at a charity ball at the weekend, in sharp contrast to her haggard appearance at the start of the year.

Whitney, who filed for divorce from husband Bobby Brown earlier this month after separating last month, is believed to have been through rehab twice since then to beat rumoured addictions to crack cocaine.

An onlooker at the Beverly Hills’ event, the 17th Carousel of Hope Ball, said: “Whitney looked really great. No one could take their eyes off her. It was impossible to imagine this was the same woman photographed at such a low ebb earlier this year.”

Another fellow partygoer added: “She was stunning. What a difference a year can make.”

Whitney is thought to be recording a comeback album for release early next year. It will be her first new release since her ‘Just Whitney’ album in 2002.
