Posted on 13th August 2009 12:00PMSienna Miller has introduced her family to her new boyfriend.
The 'G.I. Joe: The Rise of Cobra' star - who began dating George Baker, a "psychedelic trance" DJ known as Slinky Wizard, last month - took her latest beau to a pool party at her step-mother Kelly Hoppen's villa, in Ibiza, Spain.
A source said: "Sienna and George are really quite besotted. They haven't been dating for long but decided to just go for it and get away for a sunshine break. Sienna and her step-sister Natasha had organised a surprise 50th birthday for Kelly, and Sienna invited George along too so they could meet informally over a few glasses of champagne.
"He seemed pretty nervous about meeting the family but it went really well, and he was utterly charming to everyone."
At the party - which was also attended by Stephen Dorff and British comic star David Walliams - singer James Blunt tried to flirt with Sienna, but the blonde beauty rejected his advances.
The source added to Britain's Daily Mirror newspaper: "James Blunt didn't realise Sienna was spoken for and seemed keen on getting to know her better - until George got wind of it, and swooped in to rescue her."
The 27-year-old actress - who has previously dated Jude Law, Rhys Ifans and Balthazar Getty - met George earlier this year and took him to the Secret Garden Party music festival last month.
