Timberlake and Diaz share uncomfortable kiss

Justin Timberlake and Cameron Diaz kissed uncomfortably at the US 'Shrek' premiere, the third film in the animated series.

The pair split late last year and the premiere was the first time they had been photographed together since the break up.

Cameron, who voices Princess Fiona in the film walked the red carpet in a short pink Chanel dress with co-star Mike Myers.

Only a few steps behind, Justin, who plays would-be King Arthur, smiled for fans.

During interviews the couple did their best to avoid eye contact. However, they were forced together for the cast photograph, greeting each other with big smiles and sharing a hug and a kiss.
