On Wednesday Feb. 4 at 9 p.m., CBS News will broadcast KATIE COURIC’S “ALL ACCESS” GRAMMY® SPECIAL” on the CBS Television Network. Couric gets personal with some of music’s leading artists as she interviews past and present Grammy® nominees, including Justin Timberlake, Lil’ Wayne, Katy Perry and Taylor Swift.

With six wins already under his belt, Justin Timberlake could add a “Best Pop Collaboration with Vocals” Grammy® for his performance on Madonna’s hit “4 Minutes featuring Justin Timberlake and Timbaland,” which Timberlake and Timbaland also co-wrote and co-produced. From performing, producing and running a label, to his clothing line and charity work, Timberlake’s talent seems boundless. Couric gains a rare look inside this expanding empire when she gets up close and personal with Timberlake to show why this charming and savvy artist is one of entertainment’s enduring stars.

“Couric has an innate ability for getting people to reveal themselves in a uniquely intimate way,” says executive producer Susan Zirinsky. “This broadcast highlights her talent and showcases a new side of these celebrated artists like Justin Timberlake.”

Garnering eight Grammy nominations for his album, “Tha Carter III,” including Best Rap Album and the coveted Album of the Year, Lil’ Wayne is the most nominated artist of the year. With six million units sold in his 13-year career, the New Orleans native is at the top of his game. Lil’ Wayne walks Couric through his journey from impoverished childhood to being hailed as one of the best rappers of his generation.

Nominated for Best Female Pop Vocalist for her hit “I Kissed a Girl,” Katy Perry has proven that she’s more than just a pretty face. Perry talks to Couric about her upbringing as the daughter of former hippies turned devout pastors, and her evolution into a pop music powerhouse, whose irreverently rebellious songs have stirred a little controversy on their way to the top of the charts.

She’s still shooting for her first Grammy win, but Taylor Swift has already solidified her future as a rising star. Nominated last year for Best New Artist, the 19-year-old’s latest album “Fearless” has spent six weeks at the top of the charts, making Swift one of the industry’s hottest artists. Couric hits the road with this young star and her mother to find out what’s behind music’s “It” girl.

Grammy nominees Jonas Brothers, Carrie Underwood, Metallica, Ne-Yo, John Legend, Rascal Flatts, Duffy, Adele, Kid Rock, Jazmine Sullivan, Jordin Sparks, T-Pain and others will appear on the broadcast and online.

ALL ACCESS kicks off CBS’ road to the THE 51st ANNUAL GRAMMY® AWARDS, to be broadcast live from The Staples Center in Los Angeles, Sunday, Feb. 8 on the CBS Television Network. Lil’ Wayne, Katy Perry and Carrie Underwood are among the artists performing at the music industry’s premier event. Other performers include Jennifer Hudson, Coldplay, Jonas Brothers and Kenny Chesney.
