Julio Iglesias, 57, and longtime girlfriend, Miranda Rijnsburger, welcomed twin daughters Tuesday, born at L.A.'s Mt. Sinai Medical Center, according to his spokeswoman. The couple already has two sons, ages 2 and 3. The Latin heartthrob is also the father of three adult children from his first marriage: a daughter Isabel, who is a Spanish-language TV personality, and sons Enrique and Julio Jr., both singers like their old man. Meanwhile, the Latin Academy of Recording Arts & Sciences has named Iglesias Person of the Year. He'll receive the honor during a tribute on the eve of Sept. 11's Latin Grammy Awards in Miami.
