OK, here it is...

I've been trying to figure out the name of a movie I watched a while back. Its about these 2 high school teenage girls who hate each other and are complete opposite (ones blonde and popular and the other is a brunette, I think). I remember parts of the movie:
- the blonde ruins the brunette's project, which is a group of venus fly trap plants by giving them potato chips and taking some of the plants as her own. In order to retaliate, the brunette puts something stinky in her locker and makes stinks up the whole school or something like that.
- then further along in the movie, the 2 girls have to live in each other's houses and they ultimately figure out that the other girls life isn't as bad as they originally thought

I think it was one of those disney channel movies but I can't remember, I was looking for that movie too, if you figure it out let me know

I saw that I think its called the great mom swap with valerie harper
