Louis Tomlinson's mum Johannah has revealed the meaning behind one of his chest tattoos.
'For those who have asked me about the '78' tattoo on Louis chest.....It was the house number of his Nan & Grandad who he adored xxxx,' Tweeted Johannah - known as Jay - last night.
The 1D lads are big fans of tattoos and Louis' body art collection includes a bird on his right arm, a stag on his bicep and 'The Rogue' scrawled across his ankles.
Niall Horan is the only member of the group believed to be ink-free.
The boys jetted to Australia for the final leg of their Take Me Home world tour at the weekend - but it seems Louis is suffering from lack of sleep.
'Still not managed to get into the time zone :( feel like a zombie,' he Tweeted yesterday.
