They are as beautiful as jewels 
and as sweet as romance.
.إنّها جميلة كالجواهر وحلوة كالرومانسية
Sie sind so schön wie Juwelen
und so süß wie die Liebe.
Son lindos como joyas
y dulces como el amor.
Son bonitos como joyas
y dulces como el amor.
Ils sont beaux comme des joyaux

e dolci come una storia d'amore.
São belos como joias e
doces como uma paixão.
Они прекрасны, словно драгоценности
и сладки, словно любовь.
