Yes , you can.

To connect your Twitter account and your Facebook profile:

Log in to the Twitter account you want to associate with your Facebook profile.
Go to your Settings menu's Profile tab .
Scroll to the bottom and click Sign in to Facebook and connect your accounts.
When prompted, select the privacy settings for who will see your Tweets posted to your Facebook wall. It is set to public by default.
Click Log in with Facebook and enter your Facebook login credentials.
