It's a big week for the Band Perry. Grammy nominees in the all-genre Best New Artist category, the sibling trio are going into Sunday's awards show with the No. 1 song on country radio. 'All Your Life,' the fourth single from the band's platinum-selling debut album, sits on top of the Billboard country radio chart.

The Band Perry will perform the ballad on Wednesday's (Feb. 8) episode of 'The Ellen DeGeneres Show.' (Check local listings here.) Then they'll head to the stage of L.A.'s Staples Center, where they'll accompany Blake Shelton and Glen Campbell in a tribute to the legendary 'Rhinestone Cowboy.'

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

'All Your Life' is the second career chart-topper for The Band Perry, following the CMA award-winning No. 1 hit, 'If I Die Young.' The romantic tune has also succeeded in prompting some fans to get down on one knee.

"Two times while we were playing ['All Your Life'], two guys proposed to their girlfriends," Neil reveals.

"We've gotten so many invites to come play it at people's weddings ... which is a huge honor for us, too," adds Kimberly. "Folks even want us to be a part of that day. So, it'll be getting a few folks down the aisle."
