Shakira is pregnant. The “Hips Don’t Lie” singer announced Wednesday on her Web site that she and soccer player boyfriend Gerard Pique are expecting their first child together and are therefore postponing “all the promotional activities planned over the next few days,” including Shakira’s performance this weekend at the iHeartRadio Music Festival. It’s been a big week for Shakira, who also was named one of the replacement hosts for “The Voice.”
