Wondering how Liam Payne of One Direction has such beautiful pearly whites? Turns out, he's got some great connections -- not to dentists or plastic surgeons, but to ... the tooth fairy.
Liam says he used to be pen pals with the tooth fairy, but there's a twist: He knew the whole time that there was no such thing!
"We used to write little notes to the tooth fairy and mum, bless her, used to write back," he revealed to Top Of The Pops (via SugarScape). "I think I always knew it was my mum though -- I saw her doing it once and was like, 'What are you doing?!'"
We wonder how much his mom saved on stamps once he finally caught on ... and if Santa Claus had the same handwriting as the tooth fairy did!
