Composed: Lady Gaga looks glamorous and calm as she arrives at LAX today
Lady Gaga has called in police after her website was hacked, resulting in the theft of thousands of names and email addresses.
Her U.K. site was hacked into by US cyber attackers SwagSec, prompting her record label Universal to take urgent action.
A source told the Mirror newspaper: 'She’s upset and hopes police get to the bottom of how this was allowed to happen.'

However, the 25-year-old contained all this inner turmoil under an unusually elegant facade as she arrived at LAX today, though by the time she had arrived in New York, it was back to business as usual.
Wearing a long-lace dress, a Gothic Gaga growled at the cameras, perhaps betraying her real feelings after a spate of fresh controversy.
Earlier she'd left Sydney wearing a typically ostentatious rubber outfit, which must've proved too uncomfortable to travel in, even for her.
The cyber attack happened on June 27 but those responsible didn't make the information public until this week.

A death threat was also issued against the singer, and the gang then outrageously branded the singer homophobic.
Gaga recently hit back at claims that she's exploiting her gay fan-base, calling suggestions 'ridiculous.'
Universal said yesterday: 'The hackers took a content database dump from www.ladygaga.co.uk and a section of email, first name and last name records were accessed. There were no passwords or financial information taken.'
