I just checked on Little Dude and Bubbles (KillerBee het Axanthic x Axanthic) who have been paired on and off since October, and have never managed to do anything (at least that I've managed to witness), and they were locked! I tried to get a quick pic, but It wouldn't come out without a flash (stupid phone). I'm just so excited/relieved to see them finally get with the program.
