The 8-year-old, who is suffering from a life-threatening liver condition, asked the heartthrob several questions before adorably proposing to him. Naturally, he accepted.

"Hey Beliebers! Join us in congratulating @JustinBieber on his 200th wish & help us grant even more," the Make-A-Wish Foundation tweeted while also thanking Bieber "for granting so many amazing wishes."

"This is what it is about," replied Bieber. "Honored yesterday. one of the best moments ive ever had. thank u. looking forward to doing more together. thanks."

Bieber's manager, Scooter Braun, also took to Twitter and wrote, "Just watched @justinbieber grant his 200th make a wish!! Most ever by any musician! Very #Proud," along with an Instagram pic of the singer and Annalysha.
