Kacey Musgraves performed her current single, 'Blowin' Smoke,' on 'The Tonight Show With Jay Leno' last Friday (July 26).

The second single from the fast-rising singer-songwriter's debut album, 'Same Trailer Different Park,' describes a group of waitresses talking trash while on a smoke break from work. Musgraves co-wrote the song with top Nashville songwriters Shane McAnally and Luke Laird.

It is the follow-up to her career-launching hit 'Merry Go Round,' which helped propel the 24-year-old's debut album into the No. 1 spot on Billboard Top Country Albums chart upon its release in March.

Musgraves is currently on tour with Kenny Chesney. This fall she will join Kip Moore as a special guest on Lady Antebellum's newly-announced Take Me Downtown 2013 Tour, which kicks off Nov. 8 in Southaven, Miss.
