Ben Affleck and Jennifer Lopez are taking their relationship to another level by blending their families. After seeing the couple with their children last week, the actor performed some solo daddy duties this time with his children, Seraphina and Samuel, and his girlfriend's son, Emme.

Affleck and the children were enjoying a family outing at the Universal City Walk, though without Violet, Lopez and the latter's other kid, Maximilian. Seraphina and Emme are about the same age, while Samuel is younger than them. He is only nine and they all look friendly.

The four had their hands full - holding a bag of snacks and drinks. They had some adult companions, who could be the children's nannies or some security guards.

According to TMZ, this is a big move for Lopez and Affleck's relationship. In fact, it was the same thing that the 51-year-old singer did when she was still engaged with Alex Rodriguez.

Their children were usually hanging out together and now, Bennifer is doing the same things with their children.

But before Affleck spent some time with Lopez's kid, Lopez herself already bonded with Samuel. The two hung out together in the Brentwood neighborhood.

They were also with Affleck and Emme. "Jennifer looked so happy to be exploring one of Ben's go-to neighborhood spots," an insider told E! News.

At one point, J.Lo rubbed her hand on Affleck's back as the children enjoyed talking. Everyone was having a good time - laughing, smiling and engaging in a fun conversation.

The source said they looked like one happy family. Luckily, people respected their family time and they were able to enjoy their lunch without any interruption.

The tipster added Lopez and Affleck "looked so happy" - walking arm-in-arm with their children. The blended family sightings come after the reports emerged that the pair would be moving together soon.

It appears they want to be involved in their respective children's lives - bonding and introducing them to each other. Lopez was even seen with her kid Max - touring a school in Los Angeles, where they would move in.

Though "The Hustlers" star had been doing this thing before, it was the first time that she was spotted with her kid.

Anyhow, despite these plans, a different source told Us Weekly Affleck and Lopez were not rushing anything in their romance. They were both committed to spending the rest of their lives with each other after discovering true love with one another.
