Careful the wind doesn't change! Jade Thirlwall is caught pulling a face as Little Mix attend signing

It looks like Jade Thrilwall might have been feeling a little bit silly during a signing at a book store on Sunday.
The singer went cross-eyed and puffed out her cheeks as she sat writing autographs in Barnes and Noble, in Los Angeles.
Jade made the funny face for just a few seconds, but it was long enough for her look to be caught on camera.
