Out shopping solo for wife Jada Pinkett's Christmas gift, in-a-rush Will Smith picked out a gorgeous $7,000 emerald necklace-bracelet set and said he'd pick it up in a couple of days. When he went back to the store, a new clerk handed him a box -- and a bill for just $3,000! When the star protested that his item had cost $7,000, the clerk opened the box and -- UH-OH! -- it was a gorgeous watch engraved with Will's name! Turns out wifey had come in the store the day after and ordered hubby's gift! The red-faced clerk stammered apologies for the mix-up, but good-natured Will just chuckled and said he'd act surprised on Christmas Morn.
