So no wonder Brandi Glanville wants to have a civil sit-down with her kids' future stepmom...
Glanville, who has two children with Cibrian, told E! News today that she planned to meet with her sworn enemy pal-in-the-making next week.
Rimes and Cibrian controversially hooked up last year after starring together in the TV movie Northern Lights. They fought off rumors that they were an adulterous item for months until Cibrian filed for divorce from Glanville that August and Rimes moved to detach herself from her hubby of seven years, Dean Sheremet, barely a week later.
Rimes took quite a bit of heat for shedding her innocent popster image, and apparently it's not easy to forgive or forget: Readers actually complained about Shape putting her on the cover just weeks ago.
"You had two couples whose marriages didn't work who really stumbled upon each other and fell in love," she said in an interview with ABC News that aired yesterday.
A rep for Rimes had no comment.
