The Broken Heels singer is hard at work on her third record, and laying down a huge amount of tracks for it, which she will then choose the best from for the final album.
She said: "I've actually built a studio in my house, downstairs, I'm literally in it every day, recording, l'm flying to the states a lot, I've been in Los Angeles and New York a lot, and if the producers cant' fly to me I fly to them.
"I have recorded maybe 15 songs, I usually do 60 to 70 songs for an album and whittle it down. It stretches me, I've been doing two songs a night."
'I just want people to hear my voice'
Alexandra, 24, has also been writing plenty of the material she is recoding, but her focus remains singing.
She added: "I co-write a lot. For me, a song is a song, I mean, [singer] Daniel Bedingfield wrote his biggest hit in his bedroom. It could come from anywhere, as long as the lyric is great, the melody is great and it's a great song. I just want people to hear my voice.
"I don't want that to sound cliché, but as an artist you want people to hear what you do best."
She's also been getting advice from her famous neighbour, One Direction star Niall Horan.
Alex added: "We're always chilling out together, we were in the studio - not working together, but just chilling, listening to music - but he's one of my really good friends and he's a great boy.
