'Just friends' Gwen Stefani, Blake Shelton snapped cuddling

Gwen Stefani and Blake Shelton might claim that they are just friends, but their recent PDA says something else.

The duo was snapped getting cosy at Adam Levine and Maroon 5's Halloween party in Studio City, California, reports E! Online.

In the pictures, Shelton is seen wearing a rocker wig and a headband, holding Stefani close with his hands on her shoulders that eventually slides down to her waist and then on to her butt.

Sources claim that the duo is seen spending time with each other a lot.
