Pop princess Britney Spears today celebrates her 30th birthday.

Since her controversial debut hit Baby One More Time as a 17-year-old back in 1999 she’s released seven albums, had five world tours and sold many millions of records worldwide.

She’s also endured several dark moments in her personal life. Her first marriage lasted a mere 55 hours, she got involved in Kabbalah, married dancer Kevin Federline and started a family.

She divorced Federline in 2006 and soon after suffered a public meltdown that included her shaving her head and a stint in rehab. She recovered to release the acclaimed album Blackout late in 2007.

The following year she lost custody of her two children but later bounced back with the subsequent Circus album and tour. Her most recent album, this year’s Femme Fatale, has also been a massive success.
