Lady Gaga and her fiance, Taylor Kinney, have ended their 5 year relationship … TMZ has learned. Sources close to the former couple say they parted ways earlier this month — no word on who pulled the plug. Gaga and Kinney have been noticeably absent from each other's lives lately … at events and on social media. Gaga was seen without her engagement ring last week in Malibu — the same day Taylor celebrated his 35th birthday. She's in Cabo right now … without a ring.
