18 year old Willow Smith is going viral this morning! The Paparazzi leaked pictures of her in a thong bikini taken while she was on vacation with her family.

The entire Smith family - including Will and Jada - are on a yacht vacation in the Mediterranean. Jada posted these pics/video from their excursion:

But it's not Jada's pics that are going viral. Willow was spotted on the yacht - wearing a very revealing THONG bikini.

And apparently, the 18 year old has a really cute shape - just like her mama.

Here are the images:
