Lykke Li was born under the name Li Lykke Timotej Svensson Zachrisson.  Here is a photo of Lykke Li standing next to a woman named Zara.  I'm not sure who Zara is or what her full name is because the Inernet has no information about her.  But the H&M Advertisement campaign claims that the woman standing to the right of Kykke Li is goes by the name of Zara.  So I'll go with that claim without further information available.
