swift001Taylor Swift has sold more than one million copies of her new album after its release in the US.

The country pop superstar’s latest long-player Speak Now debuted at the top of the Billboard album chart this week.

Billboard.com said it’s the biggest debut since 50 Cent’s The Massacre five years ago.

According to Nielsen SoundScan figures, Speak Now sold 1,047,000 copies since it was released last week. That’s slightly higher than the 1,006,000 posted by Lil Wayne’s Tha Carter III in 2008.

Speak Now is 20-year-old Taylor’s third album.

“I… Can’t… Believe… This… You guys have absolutely lit up my world. Thank you,” Taylor tweeted.
