THEY have already had the baby and their commitment is as enduring as any wedding ring, but Aussie actress Isla Fisher and Sacha Baron Cohen have again postponed their nuptials due to heavy work schedules.

The Hollywood-based couple, who welcomed their first-born daughter Olive last year, originally planned to tie the knot later this year.

But their stellar careers are keeping them from saying “I do”, with both stars in constant demand for big screen projects.

While Cohen is channelling all his energy into the hugely anticipated Borat follow-up film Bruno, Fisher has spent the past four months shooting Confessions of a Shopaholic in New York.

“It’s going to happen, it’s just hard for them to find the time at the moment,” a source close to Fisher told Confidential.
