Sienna MillerSienna Miller is reportedly back together with on-off boyfriend Balthazar Getty.

The couple began dating in June but last month were rumoured to be arguing over whether Balthazar wanted to return to his estranged wife and their four children. Sienna confirmed a split earlier in the month - telling reporters she was “single .. and I’m completely happy with that” - but the pair were spotted looking loved-up in London yesterday.

They were first spotted walking Sienna’s dogs near her home in Maida Vale, with an onlooker telling the Sun: “They looked so much in love.

“Sienna was clutching Balthazar’s hand and giggling as they strolled along together.

“She was like a teenager.”

Later, they were spotted leaving Italian restaurant San Lorenzo in Knightsbridge after a lunch date, then visited Soho’s Groucho Club in the evening - although made efforts to arrive and leave separately.

A source close to the Factory Girl star added: “They’ve talked a lot. Things are back on track.”
