If closets could speak, I think they would say a big thank you to Sienna Miller for rescuing them from a life of terminal boring-ness and providing them with a wealth of fabulous items. Thanks to her eclectic, avant-garde, anything-goes style, Sienna has cultivated a signature status as one of the world’s most celebrated style icons, one which she has kept firmly intact pretty much since the first time she ever graced a red carpet. That’s why I’m using her as my muse for this week’s Stylehiving, drawing inspiration from the super-chic ensemble she recently sported while promoting her new flick The Edge of Love during the Edinburgh International Film Festival.

Sienna Miller supposedly is putting her London home on the market because she has too many memories in it—both with her most recent boyfriend, Rhys Ifans, and with Jude Law. This got us to thinking—would we move if a live-in boyfriend moved out?

“When his name is mentioned, it makes me smile like a fool because I instantly think of him and it makes me happy. He does just make me happy. I totally love Rhys.” —Sienna Miller, talking about boyfriend, NOT fiancé, Rhys Ifans [Elle U.K via JustJared]

The hot new fashion trend this spring is having your own clothing line. Paris Hilton, Jessica Alba, Sienna Miller, Jessica Simpson, Hilary Duff, and all the girls from The Hills do. And now, Britney Spears may be adding her name to the long list of celebs whose mediocre clothes we could care less about.  That’s right, after sporting avant-garde looks like bloodstained white panties with ripped fishnets and no pants this past January, the pop tart has caught the eye of Ed Hardy. Known for their tattoo-style skull and tiger t-shirts, it looks like Ed Hardy may be willing to put an even scarier icon in their repertoire, the Britney. Yesterday she met with their fashion mogul about designing for the brand. Although she can’t seem to make a court appearance, Spears is always available to pick up some free schwag.  But, to be fair, Brit didn’t just horde all the stuff for herself, she asked them to send some clothes to her pregnant sister, Jamie Lynn, who is celebrating her birthday today. Aw, what a thoughtful big sis. So hopefully, this is a sign Britney is back on the road to recovery, because her freakish public mess is so out this season. [Dlisted]
