The 45-year-old actor has been dating the 'Saturday Night Live' producer since July this year, and he is now believed to have introduced her to his former flame Jennifer - with whom he has Violet, 11, Seraphina, eight, and Samuel, five - during a late afternoon lunch over the weekend.

According to sources, Ben and Lindsay met up with 45-year-old Jennifer - whom Ben married in 2005 and split from in 2015, before filing divorce papers in April this year - at Farm Shop in Brentwood, California, where they enjoyed a bite to eat before heading back to Jennifer's home.

A source told X17: "Ben and Lindsay looked so happy to finally be making their relationship legit with Jen. They've had to tiptoe around and Jen has resisted having the kids hang out with Lindsay. Ben was dressed up and seemed to really want to make a good impression on Jen - like how clean and healthy he looks. Lindsay looked a little nervous but was getting support from Ben."

Their reported meeting comes after '13 Going On 30' actress Jennifer was said to have no problem with the pair's romance.

An insider said previously: "Jen knew about the new relationship and still chose to go on vacation with Ben for the 4th of July. She is okay with it."

Ben and Lindsay are believed to have met in London over the summer, where Ben was working, and have enjoyed a number of dates, including going to see Sam Mendes' play 'Ferryman' in the English capital.

A source said at the time: "They are in the early stages [of their relationship]. It's more than a summer fling. They are having fun and care for each other. It's early and they are taking it slow."
