Sources told TMZ the former NBA star hung out on the red carpet at the event, which was held in Boca Raton, Fla.
Electra reportedly saw Rodman and waited in her limo for an extra 25 minutes in order to call in more security.
By the time she made it to the end of the red carpet, Electra politely greeted Rodman, who told her he loved her and asked her to marry him again.
Sources told TMZ Rodman was kicked out of the party but repeatedly sneaked back in.
Electra co-hosted the Halloween bash with Jonathan Cheban, the founder of www.TheDishh.com.
