In a video which has been doing the rounds on TikTok, the 'New Rules' singer can be seen strutting her stuff on stage in a sparkly silver bodysuit and matching ankle boots.
Spotting the man in the crowd she says: “I’m trying to read your t-shirt, what does it say? It says ‘Marry me Dula peep’," in reference to a nickname the fan had given her.
She can be seen giggling while the crowd goes wild at the request.
The 26-year-old superstar goes on to say: “Unfortunately I can’t marry you, but I can dedicate this song to you if you’d like?”
The man with the t-shirt says: “For me?”, to which she responds: “For you.”
The 'One Kiss' hitmaker then playfully gets on her knees and dances as she launches into her next song, 'Good In Bed'.
