Lady Gaga may have walked the Grammys red carpet solo on Sunday, but you better believe her fiancé Christian Carino was there to support her on her big night. Following her chill-inducing performance of "Joanne (Where Do You Think You're Goin'?)," Mother Monster was photographed backstage getting cozy with the talent agent, marking the couple's first official appearance since they got engaged this past Summer. Gaga is also nominated for two awards tonight, including best pop vocal album, so best of luck to her!
