The 'Marry The Night' singer joined several other ladies as a bridesmaid for her friend Bo's nuptials.
Lady Gaga served as a bridesmaid and maid of honour to her childhood best friend over the weekend.
The 'Born This Way' singer was pictured attending the wedding of longtime friend Bo O'Connor at the nuptials in Cabo San Lucas, Mexico on Saturday (8th June), where she looked demure and sophisticated in her bridesmaid gown.
Lady Gaga wore a light pink halter-neck style dress for the ceremony, similar to the rest of the bridesmaids at the event, while she wore a pale pink flower in her hair, which was worn down and wavy.
The 'Marry The Night' star played the part of the dutiful maid of honour well by carrying the bride's bouquet and her wedding dress train throughout the wedding ceremony.
