Ellen's Perfect Portia

Ellen DeGeneresThis Hollywood couple are so sweet it's enough to make your teeth hurt.

And Ellen DeGeneres just can't contain herself...

She says she's been happy in relationships before - but not the kind of happy that she feels with Portia de Rossi.

Ellen, who's set to host the Academy Awards, told The Advocate that she has reached a different level of contentment with her actress girlfriend of two years.

"I could say the same thing I've said in every relationship: 'I'm happy.' But there's happiness and there's love, and then there's completion." the Emmy-winning talk-show host said.

"It doesn't take away from any of the relationships that I've had, because I've had amazing relationships. But I feel like I found my perfect fit."

Ellen DeGeneres and Portia de RossiEllen says one key to their happiness is that they learn things from each other: "She's taught me lessons about myself, and I feel like I've taught her.

"We've both changed and grown, and we just feel like, 'Oh, OK, this is completion.' "

So, things seem to being going well, then?
