Perhaps, one of the worst kept secrets, but Jennifer Lopez has finally confirmed to Us magazine that she is indeed pregnant with Marc Anthony’s offspring:

Us has confirmed from multiple sources that Lopez is about four months pregnant with her first child. Or children – a source tells Us Lopez’s mother, Guadalupe, 61, “is proudly telling people she’s having twins.”

The 38-year-old singer-actress, who has long expressed her desire to have both career and kids, is ecstatic about the news.

“It’s a dream come true,” a Lopez source tells Us. “She and Marc are over the moon.”

Pregnancy news is especially sweet for Lopez, whom insiders believed was unable to carry a child at all. “[Conceiving] was a struggle for her,” says a source.

Seconds another, “This pregnancy is a miracle.”

Congratulations!!!
