A child ghost, a faux lesbian, a tabloid target and a celluloid sexpot. Mischa Barton has been many things in her 23 years, but she's never been this hot. Ten years after barfing all over herself as a squeally child star in The Sixth Sense, she's on the cover of our April issue, having blossomed into a woman who's a) developed a habit for wearing revealing bikinis on holiday; b) loves flaunting her long legs on US chat shows; and c) has cornered the market in playing pretty, posh girls. The full shoot is below, but to read Ben Wilson's exclusive interview with the sultry star of The O.C, pick up a copy of the mag - on shelves now.
