According to US Weekly, all those recent reports that Jennifer Lopez is three months pregnant? The star says don’t believe them. “No, no! We get this every week!” Lopez told Us at the September 20 party in London for her upcoming album, Brave.

Indeed, since marrying Marc Anthony, 39, in 2004, Lopez, 38, has been dogged by endless mom-to-be rumors. “I don’t mind when people talk about this,” she continued. “I get the interest. I’m not the only [celeb] who gets these rumors.” But the newest spate seems to have staying power — despite Anthony issuing his own denial: “Everyone calls about this every month . . . but, no.”

And the entertainment entrepreneur had U.K. media abuzz when she turned up at the bash in a flowy dress and drank water. Baby or no, Lopez, who launches her tour with Anthony in Atlantic City, New Jersey, on September 28, has plenty to smile about: “I’m the happiest I’ve ever been.”
