Do they make leather onesies? It's time to find out, because the worst-kept tabloid secret in Hollywood has been confirmed: Angelina Jolie is pregnant with Brad Pitt's baby.

People magazine reports that on Monday Jolie told a charity aid worker in Santo Domingo, Dominican Republic, "Yes, I'm pregnant." Reps for both stars later confirmed the pregnancy, according to the magazine. It is the first biological child for Jolie, 30, who is the mother of son Maddox, 4, whom she adopted from Cambodia and daughter Zahara, 1, adopted from Ethiopia in July.

Due this summer, the baby is also the first child for Pitt, 42, who had no children during his four-year marriage to Jennifer Aniston, which ended in divorce in October. Pitt recently began the process of adopting Maddox and Zahara, including changing their last names to Jolie-Pitt.

Friends told People that Jolie is ecstatic about the baby, due this summer. "This is a woman who values her relationships with her children more than anything," a source told the magazine. "Now she is creating a family in the context of an adult relationship."

Jolie -- who has been spotted everywhere from Kenya to England, Tokyo and Pakistan with Pitt over the past few months -- is in the Dominican Republic filming "The Good Shepard" with Matt Damon.
