American singer/songwriter Lady Gaga's Hollywood ambitions reportedly led to her split with her fiance Taylor Kinney. The 30-year-old singer and the 35-year-old actor broke up after dating for five years.

According to Heat magazine, Lady Gaga's acting career started to take a toll on the two. A source said: "The bottom line is that they don't see eye to eye on the future. She broke up with him. Probably the biggest factor is Gaga's new career."

"Gaga put the wedding on hold after Bradley Cooper approached her to appear in the film, and Taylor feels left behind," the insider added. "He would try to give her advice about the industry and she resented it. She feels she's a Golden Globe-winning actress in her own right, and doesn't need his help."

The Bad Romance singer and Kinney started dating after they met on the set of her 2011 music video You and I. The Chicago Fire actor had popped the question to the singer, whose real name is Stefani Joanne Angelina Germanotta, on Valentine's Day 2015.

"Taylor is older and keen and to start a family. He bought a secluded house in his hometown of Lancaster, Pennsylvania, in 2013, and he wanted them to live there," the source continued. "But Gaga is a city girl and loves hanging out at her house in Malibu. She's not ready to give all that up."

Meanwhile, Lady Gaga had confirmed the split on her Instagram account. She wrote: "Taylor and I have always believed we are soulmates. Just like all couples we have ups and downs, and we have been taking a break. We are both ambitious artists, hoping to work through long-distance and complicated schedules to continue the simple love we have always shared. Please root us on. We're just like everybody else and we really love each other."
