Colombian pop star Shakira confirmed that she is pregnant with top Spanish football player Gerard Pique’s baby, saying “promotional activities” were on hold to focus on her pregnancy. “As some of you may know, Gerard and I are very happy awaiting the arrival of our first baby!” Shakira said in a statement on her website. “At this time we have decided to give priority to this unique moment in our lives and postpone all the promotional activities planned over the next few days.” The “Hips Don’t Lie” singer said she would not participate in the iHeartRadio Music Festival on Friday and Saturday in Las Vegas. “I’d like to thank Clear Channel and my fans for their constant love and understanding. Big kiss! And will see you very soon!” This will be the first child for Shakira, 35, and Pique, 25, who confirmed their relationship in March 2011. NBC television announced Tuesday that Shakira would temporarily replace pop singer Christina Aguilera as a judge on season four of reality talent show “The Voice,” along with R&B singer Usher, who will sit in for Cee Lo Green.
