Here’s Sienna Miller dressed like Lolita smashed through “Dark Shadows” and taking her dog for a walk. Damn, what kind of Thorazine nightmare is Rhys Ifans anyway? Well, to date her…you get what I’m saying. Despite numerous denials of anything more than friendship between these two, Rhys has allegedly proposed to her. Good god, man. Get out of England, and find someone a little less high maintenance and irritating.

Our source reveals: “She fell about laughing, but soon realised Rhys was serious. While she didn’t give him an answer straight away, she’s since been thinking about it more and more.”

But some pals reckon the couple – who only got together a few months ago, and tried to keep their romance under wraps until they were spotted canoodling – are secretly engaged.

One friend tells us: “After telling people about Rhys’s strange proposal, Sienna’s been very coy about what her answer was. She’s been fudging the issue with mates and lots of people are starting to think that she may have even said yes.” Apparently their joint love of poetry prompted Rhys’s wacky warblings. Our spy adds: “They sit for ages jotting down little poems and reading them to each other.

How homespun of them. Jesus, all me and the boyfriend do is sit around watching “Young & The Restless” on the DVR and arguing about where to order takeout from. Sienna and Rhys are allegedly looking for a cottage in Wales to spend weekends composing poetry at. Hopefully Sienna will make like Sylvia Plath at some point. Uh, I meant write possibly incestuous-themed poetry about her father. What – you thought I wanted Sienna to shove her head in the oven? You fiends!
