Did Rihanna steal Beyonce's bedroom style?

I just stumbled on these pics of beyonce and Rihanna respectively,in the same mood and outfit.It got me thinking,was there a time when Rihanna secretly yearned to be Miss B?

Riri came out a month ago ,on her hotel balcony without make up and in her pyjamas,waving to fans,Months ago,Beyonce had done the same.Well,be the Judge
