Interview and vidio on Delta Goodrem

TOTP: Have you ever accidentally gone up to someone in the street thinking they were someone else?

Delta: Yes, I remember, even the week before I came over here, my girlfriend was coming over to say hello. It was just her, and - well, I thought it was my girlfriend - and I just walked up and waved furiously in the middle of this big corridor, and this girl sort of looked at me and waved back, like, [makes slightly scared face] "Hi!". I was like, "Yeah, hi!" and then she comes up to me and she says "Oh, Delta, how are you?" And I was like "Good!" but it wasn't my friend I was talking to!

TOTP: Has it ever happened to you, people thinking you were someone else?

Delta: Actually just before I came over here somebody said to me, "Oh, I thought you were Delta Goodrem," and I said "Oh, did you?" and they said something like "Oh, but you're much prettier than her!" I just went "Thank you, thank you very much", but I didn't really know how to respond to that!

TOTP: What proof of identity do you carry around with you?

Delta: Literally I have my library cards from school, about fifteen years ago! That's all I have, because I don't have my driver's licence yet.

TOTP: Have you ever pretended to be someone else over the phone?

Delta: [conspiratorially] Yes, but what if they're listening? I don't want them to know it was me. [Pause.] You think I'm being serious, don't you?
TOTP: Yes.

Delta: [laughs] No, no, no no no! I honestly don't, not that I can ever remember, no.

TOTP: Did they give you advice for Nina's love life?

Delta: Completely. That's all it was. I was like, "I agree, she should not go back to Jack..." Delta:
TOTP: Did you ever call one of your co-stars by their character's name?

Delta: That happens quite a lot. I used to call Conor - Patrick, his real name is - I used to call him Conor all the time. I used to say "Conor!" and he'd say [in weary voice] "It's Paddy!" I'd have to say sorry.

TOTP: Have you ever given someone a fake name because they were annoying you?

Delta: Ohh, no, I don't think so. I can't think of one off the top of my head.

TOTP: Have you ever had a dotty relative mistake you for another member of your family?

Delta: Umm...no, I don't really have any. I've only got my grandma, and I think she likes my cousin better than me, but other than that, no, my grandma's really cool and funky.

TOTP: If you could swap identities with another famous person for a day, who would you choose?

Delta: [thinks for ages] Oh God, I hate these ones, I'm really hopeless at it! [Thinks some more] Oh gosh. I've got so many straightaway, I keep thinking of all these musicians. But I can't think of one particular. [Delta asks her entourage. One of them shouts "Matt Damon!"] Delta: [laughing] Yeah, but we're going to be switching, what good would that be? Delta's PR: You could just sit and look in the mirror.

TOTP: If you were a superhero, what secret identity would you choose to have?

Delta: I'd just love magic. I'd love to be able to just click and transport. I'd be like a fairy little godmother, I think, going round hearing what people wish for and seeing what I could do for them.
