If you're a celebrity, there's one thing you can be sure of: sooner or later, the embarrassing things you've done in the past will come back to haunt you.

TMZ has got its hands on photos showing Justin Bieber wearing nothing except a guitar and serenading his grandmother.

It appears the pictures were taken in October 2012, when Justin visited his grandmother to celebrate the Canadian Thanksgiving.

The pop star reportedly slept a tad more than he was supposed to, and woke up to find that the rest of the family were already going about their business around the house.

He decided to surprise them by trading his clothes for a guitar and walking around the house singing.

Both his grandma and the rest of the family found it all very amusing, yet still urged the celeb to go to his room and put on some clothes.

“Loooove you grandmaaaa ... how are youuuu ... helloooo grandma,” the lyrics to Justin Bieber's improvised song reportedly went. Well, if this isn't real talent, then I don't know what is.

The pictures obtained by TMZ are available here.
