Sienna Miller is one smiley mama-to-be!

To prep for their first child together, the actress and her fiance, Tom Sturridge, stole some time away and jetted to Portofino, Italy for a babymoon this weekend.

On Sunday, Miller, 30, and the On the Road actor, 26 looked very much in love while strolling through the city. Along the way, they walked hand-in-hand, paused to steal kisses from each other and enjoyed ice cream cones.

With her platinum diamond engagement ring on full display, the actress, whose hair appeared to be a couple of shades darker than her normal sunny blonde hue, was all smiles during their outings.

Over the weekend, she proudly showed off her baby bump in a variety of curve-enhancing outfits. On Sunday, she sported a gray maxi dress paired with a white lace, long-sleeved top and a white fedora. She was also spotted walking around in a red sweater and black cropped leggings and dining in a chambray blouse and black pants.

In January, Us Weekly broke the news that Miller, whose famous ex is Jude Law, and Sturridge were expecting their first child together after being together for a year. A month later, she was spotted with a diamond engagement ring.

Finally, in March, the star, who had kept mum on her engagement and pregnancy, opened up about her pregnancy to British Vogue, calling her mommy-to-be status "very exciting."
