As yet it is still unknown who ended the engagement; however, the Poker Face singer, 30, was seen in Malibu without her engagement ring last week which would have been her former beau’s 35th birthday.

The pair have been together since meeting on the set of Lady Gaga’s music video for You and I in 2011 when Kinney played the man of Gaga’s dreams.

Speaking of his new fiancée, Kinney said: "I look up to a strong woman, maybe that’s why I fell for Gaga. She works incredibly hard and is very strong and inspirational like my mom, with a great work ethic."

However, despite those gushes it seems it wasn’t enough for the couple to stay together until a wedding day.
