Those who sing together ... get inked together? Luke Bryan and Jason Aldean have placed their solidarity for the Buck Commander franchise on display, tattooing the company's logo on their biceps as a form of permanent endorsement.

Aldean first shared a photo of Bryan getting his arm inked, tweeting, "In camp with my boys from @Buck_Commander getting inked up.@LukeBryanOnline is in the hot seat," just before getting the logo tatted on his own arm.

An enthusiastic Aldean then posted a photo of his own ink -- a more elaborate version of Bryan's simpler body art. Both singers are featured Buckmen, meaning they fully support the brand and Outdoor Channel show 'Buck Commanders.'

Tuesday night, Aldean took to Twitter to "set the record straight" that he and Bryan didn't exactly get 'matching' tattoos, clarifying why they got inked. "To set the record straight, me and @LukeBryanOnline did NOT get matching tatoos!!" he wrote. "We were the only 2 @buck_commander owners to not have one."

Nevertheless, the two superstars who are similarly marked in their brotherhood now have more than their 'The Only Way I Know' collaboration in common. The hit tune, which also features Eric Church, serves as the second radio single from Aldean's latest studio album, 'Night Train.'

Will Church follow suit and join his fellow country superstars and get his own companion body ink piece? Something tells us he may keep his connection to Bryan and Aldean at their current Top 15 single.
