How to enable social login for PopUp plugin

Hey I am using PopUp pro plugin for login in my site.
http://wowdesigns.in/projects/nesties/ (You can tab on "Join Us ") to see the demo.

I have used "Clean Login" plugin's shortcode for the Login form to appear.

Now I want to integrate/enable social login for the same.
Could you please help me doing this?

Hits, suggestions are welcome.

Thanks
