Sienna Miller's newborn daughter has made her public debut in London.

The 30-year-old actress stepped out for a stroll with baby Marlowe Ottoline, who was born in July, and fiance Tom Sturridge.

The four-week-old was spotted having a ride in style in the limited edition Missoni Bugaboo pushchair.

While Sienna has not publicly confirmed her baby's name or released any details about the birth, her sister Savannah set the rumour mill running after she tweeted: "Marlowe I love you..."

Sienna and actor fiance Tom, 26, who began dating in March 2011, confirmed in January they were expecting their first child.

The GI Joe actress spoke about the pregnancy to Vogue in March, revealing: "I'm in my second trimester, so I'm I-can-talk-about-it pregnant, even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years."
