Lady Gaga, Taylor Kinney Split: ‘Chicago Fire’ Actor Cheated On Fiancé? Ex Girlfriend Speaks Up

Lady Gaga and Taylor Kinney broke everyone's hearts when the "American Horror Story" actress announced their breakup. While the reason behind the split is said to be due to their busy schedules, a recent report suggests that the "Chicago Fire" actor cheated on his fiancé.

Lady Gaga and Taylor Kinney engagement has been officially called off, as the 30-year-old singer confirmed via an Instagram post that she and Kinney were no longer together. Back then, several reports claimed that the split was due to their hectic schedules with Lady Gaga filming "American Horror Story" Season 6 and Kinney filming "Chicago Fire."

However, many fans believed that there was more behind their split than the public knows. In a recent interview with Kinney's ex-girlfriend, Brittany Sackett, she recounted that Kinney cheated on her with the "Poker Face" singer, reports Mail Online.

"Taylor is weak-willed and disloyal, it wouldn't surprise me if he betrayed her too," she said.

Sackett shared that she found out Kinney was cheating on her with Lady Gaga when the actor accidentally dialed her in the middle of the night. Sackett reportedly heard Kinney in an intimate conversation and moment with Lady Gaga that time.

Sackett admitted that she was thankful to Lady Gaga for exposing Kinney's true colors to her. She expressed hope, however, that Kinney did not do the same to the "Bad Romance" singer.

Meanwhile, Kinney's co-star, Jesse Spencer, recently told Extra how he is doing after his breakup with Lady Gaga. According to the "Chicago Fire" star, Kinney is doing good.

"He's good," he said of Kinney post-Lady Gaga breakup. "Yeah, he's great."d

Lady Gaga also seems to be keeping herself busy with her friends. The "Applause" singer has been recently seen out and about with Tony Bennett at his 90th birthday celebration.
