It has been a busy week for The Band Perry as they prepare for this Sunday night's 54th annual Grammy Awards.

The Perrys are scheduled to perform on the prestigious musical awards show with country icon Glen Campbell and country superstar Blake Shelton.

"This feels like a pinnacle moment for us -- to perform with an icon on the Grammy Awards is an honor," said Kimberly, Reid and Neil Perry, in a news release.

More milestones for the band came this week.

The group's latest single, "All Your Life," reached No. 1 this week on the Billboard Country Radio Charts.

The single has already been certified gold, selling more than 500,000 copies to date.

On Wednesday, the siblings made an appearance on The Ellen DeGeneres Show, where they gave each audience member a copy of their first (and so far only) album.

Plus, one lucky audience member received tickets to the Grammy Awards, courtesy of the band.

The Perrys are nominated for the Best New Artist award at the upcoming Grammys, which will air live at 8 p.m. this Sunday on CBS.

The award for Best New Artist is presented to the person or group chosen top new entertainer of the year among all musical genres at the Grammy Awards.

"As we prepare for this weekend's show, it's a humbling vote of confidence that our song has also found its way to the top of the charts. Wow and thank you!" the band said in a news release.

The Perrys, who share a home in Greeneville with their parents Steve and Marie Perry, are currently touring and working on their second album, which is due out later this year.

The band's debut, self-titled album, released 15 months ago by Republic Nashville, was a platinum-selling success.

In addition to the most recent No. 1 song, "All Your Life," the album included the band's triple-platinum hit "If I Die Young," along with their gold-certified "You Lie" and their debut single "Hip to My Heart."

"Over a million fans already own this album, so for another half a million to buy TBP's fourth single means two things: One, the song is really connecting. Two, thousands upon thousands of new fans keep coming aboard the TBP Express!" said Republic Nashville president Jimmy Harnen in a statement.

In addition to their 2012 Grammy nomination, The Band Perry is also nominated for the 2012 Academy of Country Music's Vocal Group of the Year award.

The ACM awards show will air April 1, at 8 p.m., on CBS.

The Perrys are the reigning 2011 ACM New Artist of the Year as well as the Country Music Association's New Artist of the Year.

They earned the 2011 CMA Award for Single of the Year while Kimberly Perry was also honored with the 2011 CMA Song of the Year award.

Other honors for the band have included: the 2011 Country Music Television's Music Award for "Breakthrough Video of the Year," the "Best New Live Act" Award, sponsored by Nationwide Insurance, as well as Teen Choice, American Music Award and Academy of Country Music award nominations.

Currently, The Band Perry is performing its own headlining dates and touring as special guests on Brad Paisley's "Virtual Reality World Tour 2012," which has a show at Thompson-Boling Arena in Knoxville on March 2.

Tickets are still available for the show by calling toll-free 1-877-995-9961 or going online to knoxvilletickets.com.

The Band Perry is also scheduled to headline a sold-out show at the historic Ryman Auditorium in Nashville on Feb. 20.
