Scarlett Johansson gives boyfriend a tooth for his birthday

Ryan Reynolds gets an unusual gift

Scarlett Johansson has reportedly given boyfriend Ryan Reynolds her wisdom tooth for his birthday. The Smokin Aces star turned 31 on Tuesday but Scarlett, 22, held an early celebration for him at LA's Chateau Marmont hotel last week. At the dinner, Scarlett presented Ryan with the unusual gift.

'She'd just had her wisdom teeth removed, so she had one dipped in gold and strung on a necklace for him,' a source tells E!.

Generous Scarlett is also said to have paid for hunky Ryan to have a full body massage, but her spokesman has not confirmed the gossip.

'Scarlett was out of town for Ryan's birthday but she gave him a gift this weekend in private,' says the actress's rep. 'There was no one else there.'
