She's insisted she was single following her January split from Jude Law.
But it appears Sienna Miller is spending increasing amounts of time with rumoured new man, actor Tom Sturridge.
The handsome couple were spotted together yet again, enjoying a coffee run in London over the weekend.
New romance? Sienna Miller and Tom Sturridge go for a coffee run in London on Sunday
Looking casual in a denim skirt, boots and brown coat, the 29-year-old was enjoying a rare day off from her six days a week run in the West End production of Flare Path.
As Miller and Sturridge, 25, walked along the street side by side, they soon got company as a friend walking his dog stopped to chat.
Over the weekend, the Mail On Sunday's Katie Nicholl column reported how the pair were seen 'all over each other' during a recent dinner at The Dorchester's China Tang restaurant.
A fellow diner told the column: 'She was feeding him noodles and dumplings with solid silver chopsticks.
Just friends? Miller has claimed she is single, despite spending increasing amounts of time with Sturridge'He was rubbing her shoulders and kissing her, but at the end of the meal she seemed to get rather tearful so she paid the bill and they left in a taxi.’
Miller has been friends with Sturridge for several years and they reignited their friendship soon after she split from Law.
A friend said last month: 'They were close, but when Sienna moved to New York and got back with Jude last year their friendship cooled. They recently got back in touch and Sienna is very smitten.'
Since confirming her split from Law in January, Miller has been linked to several men besides Sturridge, including her Flare Path co-star Joe Armstrong and publishing heir Dan MacMillan.
Fancy seeing you here: The couple bumped into a friend walking his dogHowever, in a recent interview, the actress insisted she was single.
She told London's Time Out magazine: 'I'm single! Poor Joe is like, "What's going on?"
'We all find it ridiculous and laughable. I do feel very picked apart by it.
'When two people have separated and have both stated that it's amicable and mutual yet, regardless of that, it's not a nice feeling to have people talk about you behind your back and for it not to be true and for you not to be able to retaliate.'

They originally started dating in September 2003 after meeting on the set of the Alfie remake and became engaged on Christmas Day 2004.
Miller and Law ended up calling off their engagement in July 2005 after the actor confessed to having an affair with his former children's nanny Daisy Wright. They briefly reconciled before splitting for good in November that year.
