Chris Evans has sparked rumours he's dating Minka Kelly again.

An eyewitness told E! News: "Chris stayed in the car while Minka picked up the order. It was just a friendly lunch."

The pair ended their relationship last October following 13 months of dating after their conflicting work schedules put a strain on their romance, but it was believed at the time that the duo were keen to reunite when long-distance was no longer a factor for them.

A source said last year: "It didn't make sense for them to be together right now."

However, a friend previously revealed that they were trying to take their relationship slowly last year because 'The Avengers' star Chris, who was previously linked to Jessica Biel, was hurt when Minka suddenly ended their brief romance seven years ago.

The insider said previously: "She did a number on him back then. But she reached out to Chris this time. He's still a little insecure, so he's being cautious."

Meanwhile, Chris has been linked to his childhood crush Sandra Bullock after they were spotted out together on a number of occasions, but the 50-year-old actress laughed off the rumours in June.

She joked at the time: "You guys are a little behind. We've since married and it started breaking apart, so we separated. We filed for divorce, and I hope everyone can respect our privacy.

"But we're going to remain friends and share responsibility of the farm animals we've taken on, because you just can't abandon the animals."
