Not only talking about music, Nathan admitted that he didn't know Justin recently got a tattoo sleeve and couldn't wait to see it.
"Has he got a sleeve? Oh wicked, well I'm seeing him sometime soon so I'm sure I'll see him, I haven't seen it yet," Nathan said to the paparazzi.
In a recent interview with France's 'Les Anges de La Tele Realite 5 Le Mag' show, Nathan talked about Justin helping The Wanted out musically.
"We're working on it. He's written a track for our next album there's still discussions about whether he's going to sell the track or not."
The Wanted just released their first track off their new album. Listen to "We Own The Night" here!
