Beyoncé Knowles-Carter is a day away from celebrating her B'Day, and she's marking the occasion with a special anniversary edition of her sophomore album, "B'Day," out now.

The Grammy-winning singer released her "B'Day" 20th anniversary deluxe album on Sept. 3, a day before her birthday, Sept. 4. The full digital deluxe version features 31 tracks as a reissue of her second studio album, "B'Day".

The latest version includes a handful of unreleased tunes, including previously unreleased tracks "Creole," "Lost Yo Mind," "My First Time," "Back Up," and "Can I Watch You" featuring Pharrell Williams in addition to the original 2006 songs. The anniversary project also includes Spanish versions of songs like "Get Me Bodied" (Mueve el Cuerpo) with rapper and singer-songwriter Maluma and "Irreplaceable" with a sample of the late legend Selena.

Leading up to its release, Beyoncé released a deluxe "B'Day" vinyl with a 60-page collectible booklet, including "B'Day" era imagery and an anniversary "B'Day" CD.

Beyoncé first teased the anniversary project when she officially released her song "Morning Dew (Donk)" on July 4. The surprise drop kicked off a 60-day countdown for the reissue. The track, which blends smooth R&B vocals with contemporary pop production, came almost a decade after bits of the song first leaked on social media.

A month later, on Aug. 4, the singer released a remix pack including a version of "Morning Dew (Donk)" featuring her husband Jay-Z. That track came with a hard-hitting beat that combined hip-hop hits such as Soulja Boy's anthem "Donk," Sheck Wes' ubiquitous "Mo Bamba" and even a R&B classic by The Isley Brothers, "Between the Sheets."

"B'Day" was originally released on Beyoncé's 25th birthday on Sept. 4, 2006 by Columbia Records, Music World Entertainment, and Sony Urban Music. The 13-track project, which later came with accompanying music videos, became the blueprint for Beyoncé's superstar status after her successful debut studio album became the launchpad.

The album produced six singles including "Déjà Vu," "Irreplaceable," "Get Me Bodied," "Green Light" and "Ring the Alarm," which became her highest-chart debut at the time. "Irreplaceable" became her fourth Billboard Hot 100 number-one at the time. The album went on to win a Grammy for best contemporary R&B album at the 49th annual award show in 2007.

Beyoncé released an expanded "B’Day" Deluxe Edition on April 3, 2007, adding bonus tracks to the original album, including "Flaws and All," "Welcome to Hollywood" and "If." The deluxe album also featured Spanish-language versions and remixes, including "Beautiful Liar" with Shakira and "Irreplaceable."
