'Grown Woman,' Beyonce's Timbaland-Produced Single Gets Release Date

The song that was teased in Beyonce's "Mirrors" commercial for Pepsi has a name and a release date. "Grown Woman," the first single off the singer's as-of-yet untitled upcoming album, will debut on Monday, April 8.

Timbaland produced the song, which makes it slightly curious that Pepsi decided to title their spot "Mirrors," given that Justin Timberlake's just-released album, "The 20/20 Experience," features a song by the same name. Timbaland produced all of Timberlake's disc.

A number of big-name songwriters and producers are involved with Beyonce's album, including The-Dream.

In the ad, B is seen dancing in front of a mirror, as multiple incarnations of herself appear. There's the Destiny's Child-era Beyonce in a pink "Bootylicious" getup, the "Crazy in Love" Beyonce in a white tank and jean shorts, the "Single Ladies"-style hair and unitard and, of course, the modern B.

"Embrace your past," she says at the end, "but live for now."

In a seconds-long YouTube video posted Wednesday, Beyonce is shown as new music plays in the background. Text then appears and directs users to pay attention at 9 am on Thursday, offering up the hashtag #BeyHereNow as a guiding light.

Pre-announcement speculation had many thinking the singer would unveil information about her album. Rumors of a new single have been percolating for some time, so a song, album title and release date were all plausible.
