Selena Gomez has scored her first number one album in America.

The actress/singer's Stars Dance has debuted at the top of the Billboard 200 countdown, ending Jay Z's two week reign at number one with Magna Carta... Holy Grail.

It's a great birthday gift for Gomez, who turned 21 last week (ends26Jul13).

Jay Z's hit album drops to two on the new chart and the soundtrack to Disney's Teen Beach Movie rises to three.

The Kidz Bop 24 album and Marc Anthony's new Spanish-language album 3.0 round out the new top five.

Meanwhile, on the Hot 100 singles chart, Robin Thicke's Blurred Lines holds off a surging One Direction to land an eighth week at number one.

One Direction's Best Song Ever debuts at two and becomes the boy band's highest-charting hit in the U.S.

Miley Cyrus' We Can't Stop drops a spot to three, while Imagine Dragons' Radioactive and Get Lucky by Daft Punk round out the new top five.
