Jennifer Lopez and Marc Anthony were together again on Saturday — at least to promote their new project. The stars, who announced last summer they were ending their marriage after seven years, appeared on a stage to talk briefly about a new music series they are doing together. “Q'Viva! The Chosen” premieres on Univision on Jan. 28. Anthony reached down to offer his hand and help Lopez climb three stairs to the stage, and later admired the four sparkling rings on her left hand. They sat side by side on director's chairs. The two stars, along with Jamie King, travel throughout north and south America to search for artists who will come to the United States and participate in a live show of Latin music and entertainment. It airs in 12 weekly episodes in the US and on Spanish-language stations across Latin America.
