Renée Zellweger and Bradley Cooper have remained mum about their romance – but they can’t hold back their mutual feelings of adoration.

“I can’t say enough about her,” Cooper, 35, gushed to Entertainment Tonight about his Case 39 costar, whom he first met while filming the supernatural thriller. “I just love her. I [loved] coming to work. I love acting with her. I can learn so much from her.”

Echoing Cooper’s sentiments, Zellweger, 41, who recently moved into a newly renovated $4.7 million home with her beau, told ET, “[Bradley]’s a great, great actor. I just got so excited, not believing that I was going to go to work with him.”
