Beyoncé Loses Her Ring on the Met Gala Red Carpet, Jay Z Finds It and Stages a Mock Proposal!

Rapper jokingly asks his wife to re-marry him after she loses her Lorraine Schwartz ring

They saved the best for last!

Beyoncé and Jay Z were the final stars to walk the red carpet at the Met Gala in New York City Monday, and the power couple made it worth photographers' while. The "XO" singer, 32, and the "Holy Grail" rapper, 44, looked picture perfect in complementary Givenchy Haute Couture looks.

At one point, one of Beyoncé's Lorraine Schwartz rings slid off her finger and fell onto the ground. Fortunately, her husband of six years located the lost jewelry—but instead of merely handing it back to her, he decided to stage a mock proposal for the cameras. Lowering himself to a bent position, Jay Z took his wife's hand in his and slipped the ring back into place. To no one's surprise, Beyoncé said yes.

Married since Apr. 4, 2008, the "Drunk in Love" collaborators are parents to daughter Blue Ivy Carter, 2.

Next month, Beyoncé and Jay Z will kick off their 16-date On the Run tour. They will travel throughout North America, making stops in Atlanta, Houston, Miami, New Orleans, Philadelphia, Seattle and more.
