Florida Georgia Line's Brian Kelley and Tyler Hubbard will share their musical savvy on this season of American Idol. The talented duo will appear on reality singing competition for a special mentoring session with the final eight contestants.

Kelley and Hubbard will join R&B singer Jason Derulo and Scott Borchetta, President of Big Machine Records, as guest mentors. The duo will help coach the remaining contestants and share valuable advice and tips before their performances. A plethora of other celebrities have appeared on this season of the hit show, including original American Idol winner Kelly Clarkson and Boy George.

The Top 8 contestants will perform songs from the Billboard Hot 100 chart. The show airs Wednesday at 8PM ET on Fox.

In addition to offering their knowledge and know-how to the show's contestants, Florida Georgia Line will also perform the television debut of their smoking new single "Sippin' on Fire." The catchy new single — the third release from the gold-certified Anything Goes album — has made it to the Top 15 on country charts. The song follows their back-to-back No. 1 hits "Sun Daze" and "Dirt."
