Two months after announcing her pregnancy at a Miami concert November 7, Jennifer Lopez — who is seven months along with twins — opens up to Harper’s Bazaar in her first interview since sharing the happy news. “I do realize people want to know [about the pregnancy] because they’re interested, but this is the first time I’m going through this,” Lopez, 38, says of staying mum for so long. “I kind of feel like everybody knew anyway.” So why the secrecy? The singer says husband Marc Anthony, 39, was a factor. “He made me realize you can be an artist, and have credibility and success, without your life being on public display,” she says. “This is my experience and my husband’s experience, and we get to hold that for a little while.” As for how her little ones will handle the media scrutiny, the star insists her kids “will be whatever we are. . . . Private when it comes to that stuff.” Post birth, Lopez is still unsure of whether she’ll be a working mom. “I don’t know — and I like that, because my life has been so planned for so many years,” she reveals. “Once I did the tour, I really just wanted to shut it down.” For now, the singer is following that instinct. “Jennifer’s taking it easy,” a pal says. “She’s just thrilled to have the babies coming.”
