"'Ai Wo Chodai" ( "Give Me Love") 2 volumes- ongoing by Kazumi Ooya
Marumie switch careers from local news to comic act to follow the man she fell in love with. This is the first josei reverse harem that I've read. The josei reverse harem for live action (if the term is applicable) that I've seen are "Lunch Queen" and " Himitsu no Hanazono". This is the same mangaka of "Yume Chu", but the mature theme and scenes are evident in the first chapter alone.
