Keith Urban became visibly emotional while performing his regret-filled ballad 'We Go Back' at a concert in Atlantic City, just as renewed speculation swirls around his former wife Nicole Kidman's alleged romance with businessman and founder of private equity firm Regent, Michael Reinstein.
Urban, 58, appeared to fight back tears and crouched onstage during the 21 August performance at Hard Rock Hotel & Casino. The song tells the story of a man regretting letting his first love go after she has found somebody else. Urban did not identify Kidman as the inspiration.
