Justin Bieber inks again – with, er, a tattoo of his mum’s eye. After getting his 16th tattoo (in less than three years), the Biebs tweeted: "@bangbangnyc did this art, Moms always watching ;)”. A tad creepy, yes? It’s not clear whether or not the new ink was actually based on mum Pattie’s eye and we're not sure we want to know. Bieber-watch, out.
