-- After listening to Justin Bieber’s hit song “Baby” 70 times, Pakistani sisters Saania, 15, and Muqqadas Tabaydar, 13, nailed the heartthrob’s song.
"When I heard the song I forgot to eat or drink. I was just listening. I kept practicing and practicing until I learned it by heart,” Muqqadas told BBC News.
From a poor family near Lahore, Pakistan, neither sister speaks English so they meticulously sounded out the words and transliterated the lyrics into Urdu.
