They met on the set of her "You and I" music video four years ago, and now Lady Gaga and Chicago Fire star Taylor Kinney are engaged, reports Us. Gaga also posted a photo of her ring on Instagram.

The Grammy-winning artist has spent considerable time in Chicago since Kinney was cast on the NBC drama in 2012. She's also performed here several times, and she is set to return this summer to sing at Ravinia opposite Tony Bennett. 

And with Chicago Fire renewed for another season, expect to see Gaga around town a lot more. In fact, you can probably find her at one of these shops.
