Though Mario Lopez and his Dancing with the Stars partner Karina Smirnoff have not admitted that there is anything romantic between them, the pair are vacationing together in Mexico. Lopez has described his connection to the professional dancer as "a very special relationship," saying, "It's very flattering when people want to see us together and like to see us be together. We're great friends and very supportive of each other." At a recent charity event in San Antonio, Lopez told People mag, "We're definitely overdue for a break. I want to take a little time off, go to Mexico." A source close to the star confirmed that the partners left for Mexico on Sunday after spending Thanksgiving with Lopez's sister.
