The rumor mill is working overtime again. No matter how they try to squash the rumors, Blake Shelton and Gwen Stefani have been seen together again and this time holding hands at a Halloween party.

The two The Voice coaches were seen dressed in costume in Hollywood Friday night (10/30) at an A list party.

Blake was dressed in a Mexican outfit and Gwen was decked out as a sexy cowgirl. They started out the night at George Clooney's private party then left that party and headed straight to Jared Leto's house party in the Hollywood Hills.

They tried to keep it cool but was still seen holding hands off and on all night.
