Adam Lambert has showed his softer side on "American Idol," earning a standing ovation for his smooth performance of "The Tracks of My Tears."
Guest mentor Smokey Robinson, who originally performed the classic song with the Miracles, rose to his feet after watching the 26-year-old theater actor hit all the right notes during Wednesday's Motown-themed installment of the "Fox" singing competition.
Lambert, who's from Los Angeles, ditched his rocker duds for a sleek silver suit and smoothed his black hair back into an Elvis-style pompadour.
Judge Simon Cowell says Lambert delivered the night's best performance and became a star in his eyes. Fellow judge Kara Dioguardi agreed, saying Lambert showed "true artistry."
