These two are no longer trying to hide how they really feel about each other!

Sienna Miller, 29, and Tom Sturridge, 25, were enjoying more than just the sights as they walked the streets of the Austrian capital on Monday.

Sienna seems to be doing well after her break-up with Jude Law earlier this year. Good to know she's not the type to be sitting on her couch in pajamas shoveling Ben & Jerry's into her mouth lamenting her last relationship.
