MARIAH MAMA DRAMA

MARIAH CAREY is overjoyed because she believes her baby heartbreak is finally over!

Although the songbird hasn't confirmed her pregnancy, telling fans she is "superstitious," The ENQUIRER can reveal that after multiple devastating miscarriages, the 41-year-old singer is gushing to friends she's pregnant again – and this time she's confident she'll deliver the baby she and husband NICK CANNON have dreamed of for years.

As startling photos show, the Grammy winner — who recently wowed crowds at a sold-out concert in Brazil — did little to hide her expanding figure as she beamed with mom-to-be radiance.

Mariah — who suffered through three failed attempts at in vitro fertilization — “is now exuding happiness from every pore,” an insider told The ENQUIRER.

“She refused to give up hope even when she was at her lowest ebb.

Mariah is a little over three months into the pregnancy, confirmed the insider, “and she feels making it through the first trimester is an excellent sign she can carry to term."
