John Cena and Nikki Bella look sober as they dine together following split

John Cena and his former fiancee Nikki Bella looked really unhappy as they were photographed dining together on Tuesday night.

The couple were at the Cowboy Star Restaurant in San Diego, not far from where Nikki lives, and eyewitnesses say their conversation looked intense throughout the entire meal.

Nikki and Cena have reportedly been trying to work things out since Bella called off their engagement in April. Cena begged to get her back, but they haven't announced a reconciliation yet.
