Sienna Miller and Tom Sturridge have turned their friendship into a full-fledged relationship.

With a full-on kiss, Sienna Miller's romance with Tom Sturridge went from rumored to real.

Miller, 29, and Sturridge, 25, have been seen together since February, sparking speculation about the exact nature of their friendship.

But it wasn't until the pair was spotted kissing in Vienna on Monday that a relationship was confirmed ? and quite publicly, too.

The actress kept close to Sturridge as they walked around the Austrian capital. At one point, the British stars took a break from puffing cigarettes and went in for the smooch.

Miller and on-and-off boyfriend Jude Law announced in early February that they had split once again.

In an interview with The Guardian the following month, Miller denied they were engaged and said she found the amount of speculation surrounding her romantic life to be "astounding."
