Just two months after ending her engagement to the ex-MLB star, J Lo's 13-year-old son and daughter sported huge smiles in the first photos ever showing them with Affleck.
As Radar reported, J Lo and Affleck took her children to celebrity hotspot Nobu in Malibu over the weekend to celebrate the singer's sister Lynda Lopez's birthday.
Interestingly enough, the couple was caught making out at the table, which is something teenage kids definitely don't want to see their mom doing.
Despite the unnecessary PDA between J Lo and Affleck, her twins didn't seem to mind.
Emme -- who is currently sporting blue hair -- looked completely unbothered about adding one more chair to the family dinner table for her mom's new beau.
Max was photographed standing alongside the 48-year-old Justice League star without a care in the world while waiting for their car from valet at the end of the night.
Despite being used to seeing their mom with A-Rod, a source told PEOPLE that Affleck is already growing on J Lo's twins.
"Ben and her kids seemed comfortable together," an insider revealed. "The kids kept chatting with Ben. Ben seemed great. He was smiling and laughing. They ordered a lot of food to share. Ben had a Diet Coke."
"They enjoyed a Sunday family dinner together," the Nobu source continued.
"Jen and Ben sat next to each other and were very affectionate," they added. "They held hands under the table."
While Affleck has now met J Lo's 13-year-old kids -- who she shares with ex-husband Marc Anthony -- the couple has yet to introduce Max and Emme to the Academy Award winner's three children.
Affleck shares three kids -- Violet, 15, Seraphina, 12, and Samuel, 9 -- with his ex-wife Jennifer Garner.
Radar is told the new couple plan on connecting their children soon.
“Jen and Ben rushed into getting back together. They didn’t mess about jumping back into the relationship; however, they are taking things much slower when it comes to introducing their children,” sources tell Radar.
“Jen’s kids got very close with Alex Rodriguez’s family which is why they are not rushing. Both sets of children know who their parent is dating and at some point, both families will meet, just not yet," they added.
