Heiress Paris Hilton and "The Hills" hunk Doug Reinhardt called it quits in June, but now the two are back together.
"They are definitely happy again," a source close to the couple tells Us Magazine.
In May, Reinhardt told "Extra," "We're very happy. We're having a lot of fun. We laugh, we love each other. Couldn't ask for more."
Hilton confirmed the feelings are mutual, saying, "I've never been happier. We're best friends. We have the best time together. We really enjoy life. We are so much alike. I'm happy."
