Totally my new favorite celebrity couple -- Drew Barrymore and Justin Long are absolutely giddy with love for each other.

Drew went on Oprah's show to give away a million dollars to charity and, while she was there, the actress and her beau just couldn't help gushing over one another.

"She smells good," Justin told Ops, when she asked what he liked about Drew. "She's beautiful," he said, "and funny. The most compassionate person I've ever met."

Drew, who recently got back from a Mexican vacation with her honey, was "glowing", according to Oprah. The actress explained to the talk show host, "When you grow up … you decide what you want to be," and said her relationship with Justin was "healthy, productive, supportive and full of humor."

How sweet -- she actually said they're having an "excellent time."

I love them and want them to come over to play Yahtzee at my house. I love the love!
