It's on again for the on again/off again couple of musician/actress Mandy Moore and musician/blogger Ryan Adams, E! confirms. Ry recently quit smoking, and by his own admission is "happy, for the first time in my life." I always imagined Mandy to be a positive, stable influence on wild Dr. Adams, so awww. Their reunion was revealed last week when Ryan posted then removed photos of them together on the Cardinal Cave blog. Dr. Adams also posted "I guess congratulations are in order!" earlier today; that post has also been removed. But don't rule out live tweets from the honeymoon (that sounds dirty). Congrats, kids.
