Isla Fisher is struggling to master Hebrew.

The 'Confessions of a Shopaholic' actress, who has converted to Judaism for her Jewish fiance Sacha Baron Cohen, hasn't quite got to grips with the new language.

When asked if she was fluent in Hebrew, Isla laughed and said: "That would be pushing it! I know a bit, I know a bit."

Isla Fisher has defended her new movie, insisting it is relevant in the current economic climate.

The 33-year-old actress says people can "learn a lesson" from 'Confessions of a Shopaholic' - in which she plays a journalist who gets into debt because of her shopping addiction - saying it will teach people to control their spending habits.

Isla Fisher longs for Vegemite. The Australian-raised actress - who divides her time between Los Angeles and London - says the savory spread and the smell of sun cream are the home comforts she misses most.

She said: "I miss Australia - my friends, the beaches, the smell of sun cream and, of course, Vegemite! I have a dream I'll go back there one day. The people have such a positive attitude."

Isla Fisher feels "sexier" since having a baby. The "Confessions of a Shopaholic" actress - who has a 15-month old daughter Olive with her fiance Sacha Baron Cohen - feels happier about her body now than she ever has before.

She said: "I definitely feel sexier after having Olive because even though everything's going south and essentially ruined, I feel like I'm a real women now. I'm a mom. I love being a mom, just love it."
