Miranda Lambert's philosophy for her second No. 1 party: "Let's get the business over with and party!" That's exactly what she did Tuesday night, joining songwriters Tom Douglas and Allen Shamblin to celebrate four weeks at the top of the charts with 'The House That Built Me.'

The festivities were held at Nashville's trendy Sambuca restaurant in an area called The Gulch near Music Row. Miranda's fiancé, Blake Shelton, was on hand, as was labelmate Chris Young and a couple hundred friends and industry VIPs, who stopped by to offer congratulations.

Miranda, looking pretty in a sundress and boots, thanked all the people who helped get the song to No. 1 and keep it there for a month. She then paused to thank Blake. "We were driving home one night from the airport and I was listening to a compilation CD I had been given of songs that had been pitched to me. I didn't like any of them and Blake said, 'Here, listen to what I have and maybe you'll find something.' I thought to myself, 'Yeah, 'cause our music is so much alike.' 'The House That Built Me' was the third song on his CD and I cried all the rest of the way home. We immediately called and asked (producer) Scott Hendricks if he could get the hold on the song moved from Blake to me."

Miranda paused, looked at Blake and continued, "I know you didn't have to do that. You could have kept it -- except that you wanted to live," she joked before giving him heartfelt thanks for letting her cut the song. "The lyrics are amazing. I still can't sing it in concert without crying. It's my second No. 1 in a row, and I can't tell you what it means to me." (Miranda's first No. 1 was 'White Liar.')

Throughout the night the tune was described alternately as "a song written after the songwriters looked through each of our windows" and "the next song and single of the year winner." It was obvious by the various speeches that the song had touched many hearts with its message of revisiting a place near and dear to you to savor the memories.

'House' writer Allen Shamblin praised Miranda for her interpretation of the tune. "It was her vision and that passion from the beginning that carried the song and made it happen."

"It's been surreal to hear the record for the first time, in the studio, and then watch it do what it did," added co-writer Tom Douglas. "It's been a dream come true."

Miranda said if the song did receive either song or single of the year status, she could not claim credit. "This song means the world to me, and every night I try to deliver it the best that I can."

After the awards and accolades were over, guests mingled over drinks and hors d'oeuvres while listening to Merle Haggard songs ... likely a request by Miranda herself, who just may be Merle's biggest fan.
