The source said Gaga was on a luxurious six-day vacation with friends for Valentine’s Day, including her childhood best friend Bo O’Connor. The singer left Cabo on Monday, one day before news of her split was revealed. While “it seemed like the most perfect vacation,” the source told PEOPLE that “you could tell everything was not great with Gaga.” “She seemed a bit gloomy and low energy. On previous vacations, she has had much more energy and looked happier. It was obvious that she was going through something,” the source continued. Lady Gaga and Christian Carino.
