My sister went to the same school as Clare, who was a couple of grades below her. She and her sister were
the biggest bitches - I remember my sister complaining about the girls antics and rumour-spreading well before their modelling was anything more significant than Target catalogues.
I can recall when her mother infamously installed a private gym in their house. She and her sister would work out for hours before school and never touch anything that look vaguely carb-like at lunch. In an interview I read in the local paper, she claimed she's heavily involved in debating and president of the school's environmental club, which is hilarious... my sister was in their school's debating team 'til she graduated and trust me, Clare never debated in her life. And she was never the president of any environmental club.
She was a notorious liar when my sister was at the school. It looks like she hasn't changed.
