Pregnant for third time? Angelina Jolie: Not true.

Angelina Jolie has been forced to deny she is pregnant again following tabloid reports suggesting the actress is expecting her fourth biological child with Brad Pitt, according to World Entertainment News Network.

Speculation surrounding a reported pregnancy has dogged the Hollywood supercouple in recent months - rumors which were denied by the Oscar winner's publicist earlier this month.

Publication In Touch magazine - who broke the news Jolie was expecting twins earlier this year - has most recently claimed Jolie is pregnant again, reporting that the actress announced the happy news to a waiter in a London restaurant after he tried to pour her an alcoholic drink.

But the Tomb Raider star's representative, Geyer Kosinski, refutes the reports, telling Usweekly.com the claims are "not true".

However, Jolie continuously refused to confirm she was pregnant with her twins, Knox and Vivienne - even when she was sporting a huge pregnancy bump.

The news was later confirmed at the Kung Fu Panda premiere in Cannes in May after co-star Jack Black revealed all during a TV interview.
