“I have a movie I’m shooting in October ['Marry Me' with Owen Wilson and Sarah Silverman] and the movie has an album that goes with it, so I’m just a little bit busy right now, and until October, he has the World Series in baseball. We’re going to have to pick a day, pick a time and block it out, but we’re definitely talking about it,” Lopez said in an interview earlier this month.
