They have gotten married

[englishhobby]

Are both sentences grammatical and natural?
1) Just imagine! They have gotten married!
2) Just imagine! They have got married!

 

[Rover_KE]

Yes, but only American English-speakers would use the one with ‘gotten’ in it.

 

[Tarheel]

This American English speaker speaker would probably say:

Just imagine! They got married!

Or:

Imagine that! They got married!
