"Lucky" is a song by Jason Mraz and Colbie Caillat. It is the third single from Mraz's third studio album We Sing. We Dance. We Steal Things.

Lyrically, Spears tells "a story about a girl named Lucky," who is a famous pop star that, despite having all that she wants, still feels lonely inside. Veitch also commented that the lyrics actually refer to Spears' life.

Mraz was born and raised in Mechanicsville, Virginia. He is of Czech descent through his paternal grandfather, who moved to the United States from Austria-Hungary in 1915.
