Two beautiful songs in the movie Grace Of Monaco "O mio babbino caro" and Ludovico Einaudi - "Divenire"

Oh My Beloved Father  我亲爱的爸爸

It's the opera song that is sang at the end of the movie Grace Of Monaco. 
It's very beautiful, and thanks to the Internet, people told me the song's name
Here is a version of the song performed by the beautiful Angela Gheorghiu.

Lyrics from Wikipedia

Italian	Literal translation
O mio babbino caro,  mi piace, è bello, bello. Vo'andare in Porta Rossa (it) a comperar l'anello! Sì, sì, ci voglio andare! e se l'amassi indarno, andrei sul Ponte Vecchio, ma per buttarmi in Arno! Mi struggo e mi tormento! O Dio, vorrei morir! Babbo, pietà, pietà! Babbo, pietà, pietà!	Oh my dear papa, I love him, he is handsome, handsome. I want to go to Porta Rossa To buy the ring! Yes, yes, I want to go there! And if my love were in vain, I would go to the Ponte Vecchio And throw myself in the Arno! I am anguished and tormented! Oh God, I'd like to die! Papa, have pity, have pity! Papa, have pity, have pity!

Ludovico Einaudi - "Divenire"

A fatalistic orchestra piece by Ludovico Einaudi
