Thanks guys - glad I'm not the only one.

She knows lots of the other preppies - 13 out of 48 from kinder/childcare and has been to four birthday parties already this year. Sometimes it's like dropping off a rock star at school so many kids come to talk to her. So I'm not worried that she's hanging with the older kids because the preppies don't like her, I guess I'd just prefer it if she was playing with fellow preppies at lunchtime.

I guess I'll just keep an eye on the situation and see if the novelty wears off.

Nai - yes, I think it stemmed from the 'buddy' system. She had a buddy, then adopted another one who she calls her 'half-buddy' and now seems to have adopted a third.
