Gaga and Kinney first met in 2011, on the Nebraska set of her music video for "You & I." In the video, Gaga was seen in her mother's wedding dress, while Kinney acted as her love interest. Months later, the pair began dating, and remained together until May 2012, when they parted ways for one month.

"Gaga, 28, stepped out on Monday, Feb. 16, and grinned from ear to ear but appeared to not be ready to flash her new engagement ring just yet," the magazine reported. "Wearing a purple fur coat, the songstress strategically covered her ring finger with her hand and under her coat."

In a recent interview on The Howard Stern Show, Gaga joked about the possibility of tying the knot with Kinney.

"If I get married, I'll be hanging out in a pickup truck at a David's Bridal while my stylist is screaming at me," she told the host.
