Possible to get text messages from iCloud?

Trying to snoop text messages on my wifes phone. We are going through a separation and I belive there is another man. I won't go into details here but I need to figure out how to get her text messages off her phone without plugging it in.

I can't even get physical access to her phone anymore as we take turns staying at the house.

However, when I set up her iPhone 4 a year ago I turned on iCloud and it syncs her text messages. I have the password to her iTunes and she has not changed it yet.

Is there a way I can get the text messages from her iCloud without plugging in her phone to a computer?


I realize there are programs you can use to extract the text messages from a backup, but I need to find a way to get the backup I guess.
