During an appearance on The Tonight Show Starring Jimmy Fallon on Tuesday, host Jimmy asked the Friends actress whether she and the comedy star ever offer each other career advice. In response, Jennifer admitted her longtime pal doesn't always approve of her boyfriends. "If I get anything from him, it's, 'What are you doing?' Usually based on someone I'm dating," she said, before imitating Adam's voice and commenting: "What are you doing? What's wrong with you?" Jennifer went on to note that she tends to take care of her Murder Mystery 2 co-star whenever they work together.
