You and I, for life! Lady Gaga is engaged to marry actor Taylor Kinney after he proposed on Valentine’s Day, Us Weekly can confirm.

After Kinney popped the question, the couple celebrated at Gaga’s family's restaurant, Joanne Trattoria, on the Upper West Side of Manhattan, Times Herald-Record executive editor Barry Lewis told Us. On Monday, Feb. 16, Gaga, 28, stepped out in NYC, grinning from ear to ear, strategically concealing her ring finger under a purple fur coat.

The singer and her fiancé first met on the 2011 set of Gaga's "You & I" music video, which was shot in Nebraska. Ironically, Gaga wore her mother's actual wedding gown in scenes of the racy video, which starred the Chicago Fire hunk as the object of her affection. They started dating several months later, and split briefly in May 2012. The following month, the inseparable lovebirds got back together.

Since their rough patch in 2012, the stars have been more in love than ever. In a recent interview with Howard Stern, Gaga admitted that she would marry Kinney if he proposed.

"He is the right guy," she gushed of her beau. "How do we know? It's this feeling..."

Kinney, meanwhile, spoke fondly about the songstress to Us in April 2014, admitting that she pushes him to be better. "[She] is someone who’s always in your corner, that believes in you and your work, and vice versa," the Other Woman actor shared. "You know, I love what she does and her work and music and charity. She inspires so many people including myself."

As for what their wedding will look like? Gaga previewed it to Stern, joking: "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."
