Sienna Miller may be shy when it comes to talking about her personal life -- including her growing baby bump -- but she looked as happy as can be over the weekend.
The actress and her fiance, Tom Sturridge, were spotted strolling around Portofino, Italy, on Sunday, walking hand-in-hand as they took in the sights before heading to dinner.
Rumors started swirling back in January that Miller and Sturridge are expecting their first child together. The pair began dating after Miller's February 2011 split from actor Jude Law, and shortly after the pregnancy rumors came the engagement rumors, which were fueled when the actress was spotted with a ring on her engagement finger earlier this year.
"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," she told the British magazine in its April issue, referring to her goal to keep her private life under the radar.
