"Can't believe @mirandalambert has never had a #1 song before. She is soooo close this time. call your radio station and help her out!!!" fellow country star Dierks Bentley Tweeted after hearing that Lambert was just 150 spins away from her latest single, "White Liar," taking the top spot.
Lady Antebellum also put out the call, writing, "HEY! We have to get my bff Miranda Lambert to #1 this week with White Liar! Call in, request it and make it happen! Come on Lady A'ers!!!!!"
Her boyfriend, country singer Blake Shelton, rallied Twitterers as well, and Lambert – who is up for a Grammy on Sunday for best female country performance – topped the charts on Sunday, much to the delight of another Nashville pal.
"CONGRATS ON "WHITE LIAR", you're #1!! so happy for you!! xo :-)" Kellie Pickler Tweeted on Monday.
And Lambert herself marked the milestone with – what else? – a Tweet.
"Celebrate #1!!! First class all the way," she posted, along with a photo of a bottle of Korbel and a box of Swisher Sweets cigarillos.
