Mother Monster served as a bridesmaid in her best friend, Sarah Tanno's, wedding in Mexico in November 2019. Tanno, who married Tim Stewart in the beach nuptials, is Gaga's longtime makeup artist with whom the "Poker Face" singer created her beauty line, Haus Laboratories. In pics from the ceremony, Gaga wowed in a spaghetti strap dress with a thigh-high slit. The mauve color of the bridesmaid dress coordinated well with Gaga's bubblegum-pink hair as she posed on the beach at sunset. Alongside one pic of Gaga raising her bouquet in the air and smiling, the A Star Is Born actress wrote, "Two of my best friends @sarahtannomakeup and @timstewart just got married. Time to party!" Gaga also posed with more members of the bridal party in stunning beach shots and shared a video from the wedding on her Instagram.
