(Cover) - EN Showbiz - Beyonc Knowles' entire new album has been leaked online.

Her eagerly awaited fourth album, titled 4, was to be released on June 27. However, the singer and her record company will be fuming after the full 12 tracks apparently surfaced online on Tuesday. Initially the Andre 3000 collaboration Party was leaked on the internet, immediately followed by Countdown, which features a sample of Boyz II Men's Uhh Ahh.

Hours later the remaining ten tracks were found on the internet. All songs are said to be of CD quality, reports MTV News.

The singer's record company have demanded that websites remove the tracks immediately.

Beyonc's forthcoming album was the follow-up to 2008's hugely successful I Am... Sasha Fierce. Producers on the new album include Kanye West, Sia and Consequence.

The singer is currently in the UK, ahead of her headlining slot at iconic British music festival Glastonbury later this month. (C) Cover Media
