You look lovely when you’re smiling.

[englishhobby]

Which of the following is idiomatic?

1) You look lovely when you’re smiling.

2) You look lovely when you smile.

Logically, it should be the present simple in the clause, because a regular action is described, right?
Or maybe in 1) we can say "when you are smiling like this"? Then the use of the present continuous is justified, isn't it?

 

[bhaisahab]

They are both equally common.

 

[englishhobby]

Are they interchangeable (do they mean the same)?

 

[Rover_KE]

In most contexts, they would be interchangeable.

Don't ask me for a context in which they wouldn't be interchangeable. I'm just not going to say they are always interchangeable.

 

[MikeNewYork]

For me, the meaning is the same.
