Promoting Wife.................a new trend!

I dont understand why they are doing so,,,,,,,think about Humayun Sir(writer,director,teacher),Mahfuzur Rahman(chairman,ATN). 

I dont find anything special in Eva Rahman as a singer.Mahfuzur Rahman spending lots of money & time to promote her as a singer.Even ATN is loosing its popularity only because of her I must say.

On the otherhand our Humayun Sir is relentlessly trying to promote her 2nd wife to turn her into big big actress! But Why?
