Lady Gaga and celebrity agent Christian Carino broke up and called off their engagement in February. Now sources are saying it's because he was distracting her from her work. At the height of her A Star Is Born fame, Lady Gaga broke up with Christian Carino and called off their engagement, which promptly sent Gaga and Bradley Cooper stans into a meltdown because they thought this would be the moment they got together. Bradley and Gaga never ended up dating because (1) he has a family and (2) all that chemistry they had was just a little thing called acting. All that aside, the reason why Gaga broke up with Christian was for the sake of her career.
