Keeping Up with the Kardashians? Kim catches up on front-page news about her famous family as she leaves Australia

By Cassie Carpenter and Louise Saunders ..She's been apart from her famous family since she headed Down Under to promote her QuickTrim weight-loss product last week. But rather than calling her elder sister Kourtney to catch up on her gossip, Kim Kardashian decided reading a magazine would be the best way to learn what her siblings have been up to as she prepared to jet out of Melbourne Airport on Friday. Gathering snacks and reading material for the long trip home, the 31-year-old socialite was seen perusing several celebrity tabloids, including an OK! Magazine cover featuring Kourtney.

But the reality star wouldn't have been needing any style tips from her magazines, as she slimmed down her curvaceous figure by donning a pair of optical illusion trousers. The beauty, who turns 32 next month, wore the fashionable two-toned trousers in order to fake a slimmer silhouette, and paired them with a cleavage-enhancing black tank top. Kim's airport ensemble cleverly mixed casual with chic as she threw her luscious brown locks in a fuss-free top-knot yet wore sexy black stiletto heels for her 15-hour flight back to Los Angeles, California.

While in Australia, the TV star-turned-entrepreneur promoted QuickTrim at the packed Westfield Southland mall, attended an E! Channel event, and had dinner on the harbor with Spice Girl Melanie Brown. The socialite stepped out in yet another optical illusion ensemble - a black-and-red panelled dress - while attending the QuickTrim Purple Reign party at Silk nightclub. Kim put on a brave face despite the fact that boyfriend Kanye West is currently in the middle of his first sex tape scandal. It's an ironic twist for the couple since Kim originally shot to fame thanks to the now infamous sex tape she made with ex-boyfriend Ray J in 2007. Her rapper boyfriend of six months is believed to be the subject of a soon-to-be-released video recording with an unidentified 18-year-old woman who is reportedly a 'dead ringer' for Kardashian. According to Radar Online, the 20-minute video was shot in a hotel shortly before Kanye officially got together with Kim in March, and he is said to be 'terrified' about the video being leaked. Kanye has even rapped about Kim's 2007 sex tape in his song Clique. He states: 'Eat breakfast at Gucci/My girl a superstar all from a home movie.' source:dailymail
