Beyoncé Knowles has officially announced the title of her upcoming fourth studio album: 4.

In an interview with Billboard, the singer explained that she chose the name for fourth album because fans had been referring to it simply as “4.” The number also holds special significance to her.

“We all have special numbers in our lives,” she said, “and 4 is that for me. It’s the day I was born. My mother’s birthday, and a lot of my friends’ birthdays, are on the fourth; April 4 is my wedding date.”

4 has no set release date, but the lead single, “Run The World (Girls)” was released last month. The dancehall-style track contains a sample of “Pon De Floor” by Major Lazer, but Knowles told MTV that she would do some genre-bending on the new album, citing inspirations such as Lauren Hill, Stevie Wonder and Fela Kuti.

“Well, I wouldn’t say I’m inventing a new genre,” she said. “I’m mixing every type of genre that I love and I’m inspired by every type of genre.”

Knowles is also the lead actress in the Clint Eastwood directed remake of the musical film A Star is Born. The movie, which is a remake of three previous versions, is set to be released in 2012, while 4 could be released as early as June this year.
