Ryan Reynolds just turned 31, and his girlfriend Scarlett Johansson gave him one of her wisdom teeth dipped in gold and strung on a necklace as a birthday present. She'd recently had them all yanked, so it wasn't like she did it special. The actress is known for her abundant teeth, so they make a good gift. The presentation happened at the party she threw for him at the Chateau Marmont. It's said she had a much more personal gift for him when they were alone later. Probably that monogrammed tie he'd had his eye on. (Dig Spy)
