Her rep just announced she is splitting from longtime husband Christopher Jarecki, who she first met in 1997 and with whom she had one son.

Maybe the couple naturally drifted as Silverstone tirelessly championed veganism, eating fermented umeboshi plums and chewing your infant's food and then spitting it into his mouth in the name of "bonding."
Or maybe it was because she's a virgin who can't drive!
