Miranda Lambert is going to have to make good on her bet with her fellow songwriter on "Bluebird".
They promised to get a bluebird tattoo if the song went to number one, and it has. It has just become Miranda's fourth number one as a primary artist. The last time she did that was with "Over You" in 2012. Miranda thanked her fans on Instagram, saying, "I'm celebrating happiness and the feeling of artistic freedom in a time where we all feel a little caged. I'm celebrating country music and all the joy it has brought to my life. I'm celebrating ALL the fans, the writers, the musicians, the crews, and bands, radio and streaming services, venues big and small for allowing me to have the most wonderful career for the last 17 years. I have spent my life doing what I love and I feel more blessed and humbled than ever to have this song of hope resonate with you all. Thank you from the bottom of my heart."
