You've had a mad few months. How are you coping with it all?
"The last eight months of my life have been pretty insane. I don't think you can really be a total party animal and be number one. You have to pace yourself a bit. There's been lots of flying and lots of different time zones, but jetlag is really the only negative thing about this. Jetlag is retarded!"
How did you celebrate the success of 'TiK ToK'?
"There wasn't a specific thing I did to celebrate, but I did treat my mum by taking her to a spa. I'm not really a big spender so I didn't do anything outrageous. I'm just down to have a good time and I want people to have fun. People get so pretentious about pop music so I do feel like I'm fighting this battle. My record is honest and fun. It's a celebration of youth and life and going out and getting crazy. I'm about non-pretentious irreverence and f**k off good fun!"
What sort of chart position are you hoping for with 'Blah Blah Blah'?
"Obviously I hope it goes to number one, but who knows what's going to happen? I just hope people like it. It's a cool song about a woman talking to a man the way men always speak to women. If you listen to any rap or pop station, the way men talk to women is just so cheeky and a little bit degrading. I'm not offended by it though - I just think it's funny. This track is meant sarcastically. It's me throwing it back."
What's the inspiration behind the video?
"Well, it's a funny video to go with a funny song. It's set at a bar/bowling alley and all these dudes are trying to hit on me, but I'm just like, 'Really? You're so annoying!' Some guys ask you what your middle name is as if that's really going to help their chances! Their lines are lame."
So what is a good chat-up line?
"I heard a good one the other day: 'Did you just fart? Because you blew me away!' It's great, but horrible."
Have you thought about the third single from the album?
"If I could pick any song on the record, I'd want it to be 'Stephen', but I think we're going for either 'Your Love Is My Drug' or 'Take It Off'. 'Stephen' and Animal' are my two favourites on the album though. 'Stephen' shows the vulnerable side of me but it's still a funny pop song. It's me saying I'm totally obsessive and in love with this guy, but he's blowing me off in a pretty funny way. I like 'Animal' because it's one of the last songs I wrote for the record and it just embodies everything I think about humans - it's my take on human beings as an animal."
A lot of fans are comparing your music to Uffie's. In fact, the beginning of 'TiK ToK' sounds remarkably similar to 'Tthhee Ppaarrttyy' by Justice and Uffie...
"I've never heard the song, so I don't really know, but people are comparing me because they have a very one-dimensional view of who I am. You know, I only have two songs out right now. When people have a better understanding of who I am, what I stand for, what I look like and what my shows are like, I think that's going to dispel the comparisons."
I have the track here. Would you like a listen?
"Ooh I like that song! I don't see the similarity though. I understand that we're both white girls, but we're so different in lots of ways. People compared my s**t to 'Pop The Glock' by Uffie the other day and I just don't hear it. Am I crazy? I don't hear it!"
You were at the Brits earlier this month. What did you think of the performances?
"I'm such a fan of Lily Allen - I think she's so sweet! Who else? Well, Dizzee Rascal with Florence, that was amazing! Cheryl Cole gave a really good performance too, but you can really tell when someone's not singing live. It's a shame."
Are you expecting to be nominated next year?
"I'm not expecting to be but it would be badass! It would be such an honour - it's like the Grammys for the UK. I'm definitely up for performing there. I'd just love to be on that stage, you know? I'd even sweep up the glitter afterwards!"
'Blah Blah Blah' by Ke$ha is out now.
