I've seen her a lot too.  Spoke to Lohan a week or so ago, they are friends.  She said she's on vacation but the facial expression was weird, so I'm not sure.  Sounds like she hasn't permanently flown the dropped out.

if and when she wishes to return she shall. The K-girls work hard and this job takes a toll. They are entitled to take time off. Fera is both smart and sensible and no more needs to be said. In the meantime enjoy the the talent from the Divas to the newbies some of whom are sensational.
