Justin Bieber and Hailey Baldwin have attended a spiritual conference together.

The rumoured couple were spotted at Sydney's Allphones Arena today (29.06.15), where the Hillsong Church is currently holding five days of religious seminars.

The 'Boyfriend' hitmaker, 21, and the brunette beauty - who is the daughter of actor Stephen Baldwin - looked relaxed and happy as they were photographed leaving the arena together fuelling speculation they are an item.

The pair arrived separately in the Australian city with Justin taking a private jet and Hailey opting to travel on a commercial flight.

A spokesperson for the Hillsong conference confirmed the star is not performing at the event and was simply there to enjoy the seminars.

They said: ''People come from across the world to Sydney each year to attend Hillsong Conference. Justin is here - like tens of thousands of others - as a delegate who is seeking to build stronger foundations into his life.''

They added of 18-year-old Hailey's presence at the conference: ''I'm not aware of that name... Anyone is welcome to come. The conference is open to everyone.

''We don't make a big deal [out of celebrities],

''The purpose of the conference is to honour God, and our hope for all attending is that their lives are enriched.''

Justin insisted he had turned over a new leaf earlier this year following his arrest for drag-racing and assault in January 2014 and credited his ''relationship with God'' for helping him to stay positive.

He recently wrote on his Instagram account: ''I'm not religious nor do i think I have ANYTHING figured out that's why I call out on God to help me through what I can't do on my own. Developing my relationship with God has been the coolest thing I've experienced, to know that I'm not alone and I don't have to live in fear. (sic)''
