He has reportedly made quite the impression on Jennifer Lopez's mother.

And Ben Affleck is already proving himself to be part of the family as he was seen bonding with her children too. 

The 48-year-old actor was seen spending some quality time with the JLo's 13-year-old twin children son Maximilian and daughter Emme during a family dinner at Nobu in Malibu on Sunday night.

No doubt Ben feels comfortable around her loved ones as they were reportedly there for JLo's sister Linda's 50th birthday. 

Outside of the restaurant, Ben seemed to have a blast with Jennifer's kids as he was seen sharing a laugh with her daughter Emme before making their entrance.

He was also seen arm-in-arm with the 51-year-old Jennifer and even placed a loving hand on her back at one point.
