DailyMail published the lunch pics and added the new info:

"Meanwhile, the Avengers star reportedly also wants to get serious with Taylor, with a source telling the publication that he has 'wanted to settle down for a while.'

'I think he will introduce Taylor to his mates soon,' the source close to Tom added."
