Pregnant Isla Fisher glowing as she attends Vanity Fair Oscars bash

Isla Fisher may be well into her third pregnancy with husband Sacha Baron Cohen, but that didn't get in the way of the couple enjoying the glitz and glam of this year's Oscars. The Great Gatsby actress attended the annual Vanity Fair Oscar Party in Beverly Hills, California, accompanied by her other half.The 39-year-old showed off her burgeoning baby bump in a floor-length cream gown with floral detail and swept her fiery locks to one side. A pair of sparkling drop earrings and a small clutch completed the glowing look, while her husband was handsome in a tuxedo and black bow tie.

Isla and Borat star Sacha, who are already parents to daughters Olive, seven, and four-year-old Elula, are expecting the latest addition to their family to arrive in spring.Isla's third pregnancy is obviously suiting her – the actress looks toned and svelte aside from her bump – though that wasn't the case with her first two pregnancies: "I gained 65 pounds with my first baby and 70 with my second," she told Fitness Magazine last year. "I had severe morning sickness both times, so I mostly ate supersize bowls of white pasta with loads of butter and cheese because that was the only thing that took away the nausea."

The Australian actress has previously revealed that marriage is like "winning the lottery", telling Australia's Sunday Telegraph: "Choosing to be together every day is incredibly romantic. I love marriage. I think it's a wonderful institution and it's the most important decision you make. "Life is filled with highs and lows, and you have a best friend to share it with you. It's amazing. It's like winning the lottery, having a good partner. "Isla married the British comic in an intimate ceremony with just six guests in Paris in 2010, six years after they got engaged. They originally started dating in 2002, after meeting at a party.The couple welcomed baby Olive in October 2007 before she and Sacha tied the knot. Their second daughter Elula Lottie Miriam arrived in August 2010, five months after they wed.
