treat someone kind/kindly

[allthewayanime]

Is it 'to treat someone kind' or 'to treat someone kindly'?
I thought about Whitney Houston's famous song 'I will always love you' and she says 'I hope life treats you kind' therefore I am really interested if it's correct to say 'kindly' instead of 'kind'.

 

[shannico]

It should be kindly, as treat should be followed by an adverb.
Treat you well
Treat you kindly
Treat you nastily
Hope it helps.
