Backstage at Madison Square Garden, where Capitol Nashville’s Carrie Underwood recently performed as part of her Denim & Rhinestones Tour, the country star was joined by Tunnel to Towers Foundation’s CEO/Chairman Frank Siller for this illustrious photo op.

Throughout her 43-date trek, which continues through 3/17, Underwood has contributed $1 dollar from each ticket sold to Tunnel to Towers, an organization dedicated to supporting U.S. military veterans. In addition to Siller, 300 of the org’s staff, fallen first responder and Gold Star program participants and active-duty military, FDNY and NYPD also attended the concert.

Seen above just before bedazzling their own denim with rhinestones are (l-r) Underwood and Siller.
