Pixie Lott is constantly checking her chart positions.

The 18-year-old British singer - whose highly-anticipated debut release 'Mama Do' was released earlier this week - is so excited about the song, she can't stop monitoring the download charts.

She told BANG Showbiz: "Seeing it as the number one download on iTunes was absolutely crazy. I'm always looking at the iTunes homepage and just seeing it was in the top ten with my little picture, it was absolutely insane. I can't believe people are buying my song!"

The blonde beauty - who has been dubbed 'the next pop princess' - is now hopeful it will top the UK singles charts at the weekend.

She said: "So just keeping my fingers crossed and anything that happens now will be a bonus."

Until then, the pop singer has a busy few days ahead of her.

She explained: "I'm so excited. This week I'm supporting The Script and I'm doing the Isle of Wight festival and I get to have my band back. I've been touring with The Saturdays, my band haven't been allowed to come with me. I love having them back and I just get so excited when I perform with them."
