Miranda Lambert has a 5th number one single on her hands! She is at the top of the Country Mediabase chart this week with “Mama’s Broken Heart.”

The song is the fourth single off of her Four The Record album, and it has some familiar counrtry names attached to it. Penned by Kacey Musgraves, Shane McAnally, and Brandy Clark, the track has seen great success as well as critical acclaim and deservingly so. In my opinion, it’s one of the best country singles this year!

Miranda and company were very excited to hear the good news! Here is what they shared via Twitter:
