LOS ANGELES, Calif. -- The baby bump rumor mill was sent into overdrive today, when reports began to circulate online that Angelina Jolie was pregnant.

But the news didn’t stop there — X17Online.com took the story a step further, claiming the actress is carrying twins.

When contacted by Access Hollywood, a rep for Angelina refused to comment on the rumor.

“I am not commenting on an unsubstantiated rumor from a tabloid photo agency,” the rep said.

Brad and Angelina have four children – Maddox, 6, Pax, 4, Zahara, 3, and Shiloh, 1.
