Carly Rae Jepsen has revealed she's nervous about touring withJustin Bieberbecause she doesn't know what to expect.

The Call Me Maybe singer - who was [uuid=0a2b0285-2501-48e0-83df-45a577fabaaa]hit with a naked picture leak[/uuid], as well as [uuid=c733bffe-1278-40a4-85e9-59b6099a08ec]a sex tape scandal[/uuid] last week - claims she's looking forward to supporting Biebs on his Believe tour, but has no idea what will face her.

The 26-year old told MTV News: "I don't know what to expect. I did one or two shows with Justin [earlier this year]. One in London and one in Mexico City, and all I can say is, like, 'Wow'. They were huge - 300,000 people in Mexico City. I was speechless.

"[How do you] take it in? I don't know that I totally do. I think that like in 10 years' time I'm gonna sit back and look at everything that's happening to me this year and actually have a 'whoa' kind of a moment."
She added: "Right now everything's so fast and the pace of it so quick that I'm just kind of keeping my head to the ground and trying to do the best at getting through it."
Jepsen recently revealed that she will be collaborating with JB on her forthcoming LP, stating that she has been "sworn to secrecy" about her hook up with the Boyfriend singer.
She told MTV News: "The Justin song, I'm kind of sworn to secrecy on because I think we want to release it together at one moment. But the rest of the album, I'm really excited for!"
