The Disney stars have been close pals since meeting at an audition for children's TV show ''Barney and Friends'' and Demi - who entered rehab last November for three months - revealed Selena kept in constant touch throughout her treatment.
Speaking about Demi - who earlier this year checked out of rehab after receiving treatment for personal issues - Ashley said: ''I'm really happy that she's doing well. She and I never had a problem with each other. But, you know, it doesn't go away.... Jen Aniston still gets asked about Angelina Jolie.''
"They should put on clothes. Put on clothes!" Demi exclaimed. "Girls that walk around with skimpy little costumes, don't do that! It's not cute, cover it up!"
