Guess these co-workers can't get enough of each other on set! Ashton Kutcher decided to double date with his Two And A Half Men co-star Jon Cryer and his wife Lisa Joyner with Mila Kunis in tow on Wednesday night in Studio City! The couples enjoyed a meal and looked happy at dinner, before retiring for the night! As the foursome waited for their cars at the valet, congratulatory hugs were exchanged! Looks like they all had a lovely night.
