Yes, we know Paris Hilton stories are usually about her cooch, but this one's about her pooch. Remember Tinkerbell, the Chihuahua she took everywhere, but hasn't been seen for a long time? Hilton showed up to the set of The Hottie and the Nottie recently with a Chihuahua she claimed was the reclusive Tinkerbell, but which looked suspiciously like an imposter. Had there been a switch? Although Paris insists there is only one Tinkerbell, a pet expert has observed that in an older photo "Tinkerbell has a black nail, while in the new one, the nail is white. I don’t think it’s the same dog.” Has the real Tinkerbell been locked away and forgotten in a storage facility? (Celebrity Dog Watcher)
