Radha too is considered as Avatar of Laxmi along with Rukmini, if we consider Krishna as Avatar of Narayan.
In BrahamaVaivarta Puran it is different, I think. There Krishna-Radha are Supreme God and Goddess. Narayana-Laxmi are manifestation of Krishna Radha.
Oh ok. Thanks for the info. I wonder what exactly was Rukmini's importance in Krishna's life. I haven't read any sacred texts. Whatever I know, it's only from grandma's stories and serials and films and it does seem like she was the most loved and respected wife of Krishna and she was very matured and intelligent whose duties were mostly to take care of her family. I have even heard of a story where Rukmini was cursed by Sage Durvasa that sh will be separated from Krishna because she drank water before offering him. These rishis and their attitude problems! π Also there are stories of Rukmini being jealous of Radha because Krishna never loved her the way he loved Radha.
