On tvtome.com they say that it's a rumor that Mackenzie Rosman is leaving the show!
So I'm sure she's not really leaving the show! :) She's my favorite charactor on the show!

I think after this season everyone will be leaving as i think this is 7th heavens final season Good Luck

This is 7th heaven's last season, so everybody will be leaving.

I know, I was talking about then.
