"I think when somebody's desperate, they're desperate. I can't knock him for trying. He's trying everything to get his girl back, so I can't knock him for that... I talked to him personally, and we're not necessarily like the best of friends or anything, but you know, he mentioned something about that. So you can tell when somebody is in dire need of having that special person back. And I think that's all it is." Singer Jason Derulo sympathises with Robin Thicke and his public campaign to win back his estranged wife, actress Paula Patton.
