I'm The One DJ Khaled feat. Justin Bieber
Mother Monster had fast food delivered to her loyal fans.
Lady Gaga treated the supporters gathered outside her LA hotel to a surprise delivery of burgers and fries.
"Sending some yummies to Château Monster tummies!" Gaga tweeted.
The 'Little Monsters' had been serenading the 'Judas' singer while they waited for a glimpse of the star in West Hollywood, and were rewarded with a McDonald's and a hand-written note.
"Dear little monsters," Gaga wrote. "Thank you for singing to me all day and night.
"I love you with all my heart. You make everyday worth living.
"Kisses to the cops for keeping you safe. Love Lady Gaga."
