When Tim Robbins and Susan Sarandon split late last year it proved that, no matter how secure and stable a Hollywood relationship seemed, even the most fairytale celebrity romances were only mere inches from a messy break-up at any given time. While not a cataclysmic parting of Tiger Woods and Elin Nordegrin standards, Courteney Cox and David Arquette have announced that they are to undergo a trial separation, the reason for which is to "better understand ourselves and the qualities we need in a partner and for our marriage", which when translated from Hollywood PR language essentially means that their marriage is caput.

"We remain best friends and responsible parents to our daughter and still love each other deeply. As we go through this process we are determined to use kindness and understanding to get through this together", their statement continued. It may as well have said "David is collecting his things from our house on Sunday. After an intense period of paparazzi attention, he will finally snap and push one to the ground and will be detained by police who will leak his unshaven and not-at-all flattering mugshot to the tabloids. I will soon begin dating a 24-year-old South American model, allow him to call me 'Monica' and will shortly thereafter replace my BFF Jennifer as the permanent covergirl of Grazia magazine. We would politely request privacy in this difficult time."

The couple met in 1996 on the set of Scream and have recently completed work on Scream 4, which begs the question was this one Scream too far?

Oh, and David Schwimmer after marrying some 25-year-old.
