Justin Bieber has debuted his new tattoos.

The 'Flatline' singer has been building on his collection of body art since he was just 16-years-old and has now revealed the latest two additions on his Instagram account.

Justin posted a picture of himself last night (12.01.14) with his arm across his face, showing off his newest tattoo, which features a compass design on his tricep, with the caption ''New tat'' accompanying the image.

He then posted a second picture, just four hours later, of a court jester style face on his forearm in thick black ink with the words ''Coloured it in'' alongside, as he'd previously unveiled the tattoo with less colouring on Saturday (11.01.14).

Other tattoos in the 19-year-old's collection include a small bird on the pop heartthrob's hip - which he's previously claimed is a ''family tradition'' - and the logo of Canadian junior ice-hockey team, the Stratford Cullitans, on his left shoulder, which he dedicated to his Grandfather on Twitter in January 2012.

Despite having had sentimental and personal images penned on to his skin, Bieber declared his admiration for traditional designs on 'The Ellen Degeneres Show' in 2013, saying: ''I like classic, classic tattoos.''
