The 'What About Us' hitmakers are hoping joining forces with the 19-year-old singer will help them crack the US and are lining up meetings to discuss teaming up with Justin on his Believe tour, which has been extended with several more dates across the States this summer.
Mollie King told Capital FM: ''There are talks about it definitely. We're going to see how our schedules tie up really - we'll see.''
Rochelle Humes added: ''He's on tour right now and obviously we're really busy at the minute and in the next couple of weeks so hopefully if we can get out there and do some dates for him that would be good.''
The girls - who scored their first ever number one single in the UK on Sunday (24.03.13) - are big fans of the Canadian heartthrob and were lucky enough to meet him while they were in Los Angeles.
Una Healy excitedly said at the time: ''We met Justin Bieber, he was on a TV show with us and I remember I went in for the kiss on the cheek and he's got baby soft skin!''
Justin's tour hasn't gone as smoothly as planned so far, notably when he caused outrage by keeping his young fans waiting for nearly two hours at London's O2 arena earlier this month.
