Brad Paisley and Carrie Underwood will return to co-host the 2015 CMA Awards in November, marking the eighth time they have shared the honors.

The longtime friends have exploited their brother-sister chemistry and golden comedic timing on the broadcast for nearly a decade now, singing funny songs, skewering their fellow celebrities and participating in hilarious skits, taking on everything from celebrity breakups to Miss Piggy to current events with an irreverent air that has made them one of the most beloved pairings in the history of the broadcast. The first promo clip from this year's awards will air during CMA Fest: Country's Night to Rock on Tuesday evening (Aug. 4), but has already been posted online. Take a look at the clip above, which features highlights and hilarious outtakes from past seasons.

The annual event isn't called "Country Music's Biggest Night" for nothing. The biggest stars in the genre come together every year for the awards, vying for the most coveted statues of the year in categories like Male Vocalist, Female Vocalist, Song, Single and Entertainer of the Year. The broadcast also includes live performances and one-of-a-kind collaborations from many of the top names in country music, and Paisley and Underwood often provide some of the most viral moments of the night with their unique comedy blend.

They'll have their work cut out for them in 2015 if they want to top last year's broadcast, during which Paisley "accidentally" blurted out the sex of Underwood's baby.

The 2015 CMA Awards are set to air on ABC on Nov. 4 at 8PM ET.
