Loveline starts in about 15 minutes, and AVA is scheduled to be on the show TONIGHT. However I just called and mentioned the band and the screener said "they're not on tonight." He could be totally wrong or something could have changed last minute. The only thing to do is listen and see if they're on or not when the show starts.
EDIT: A friend of mine called and the screener told him that it will be Dr. Drew and Stryker, and then AVA will be on as soon as they get back from their show.
