Hi MerryA
It is better to have ugly thighs than an ugly face...

or an ugly personality, of course. So I wouldn't worry about cellulite too much! some sexy tight jeans should cover it up
I remember seeing a report that the anti-oxidants in fruit and veg were thought to help with cellulite. So being vegan is probably a pretty good start? I've also read that exercise and drinking plenty of water are recommended.
There's a programme for combatting cellulite
here: I don't know if it's any good, but you might find it helpful
