Ant Anstead’s two oldest kids experienced a few special “firsts” whilevisiting California from the U.K. for Christmas— including meeting their dad’s girlfriend of seven months, Renée Zellweger!

TheRadford Returnsstar’s daughter Amelie, 18, and son Archie, 15 — who live in England with their mom andAnstead’s first wife, Louise Storey— got to spend time with the Oscar-winning actress while visiting Laguna Beach for the holidays, Anstead tells PEOPLE exclusively.

“It was great,” the car expert, 42, says. “I mean, Renée’s so personable, and so great with people, and they’ve met a few times on FaceTime, so everybody was excited to finally get together.”

He continues: “Of course, everybody got on famously. It’s really nice.”

Anstead says he was also thrilled to see that Amelie and Zellweger had an immediate bond.

“She and Ren really hit it off. Just as two girls,” he shares of his firstborn before gushing: “Amelie’s amazing because she’s so talented, and funny, and she has this strand of kindness just running through her. She’s just this really kind, solid human.”

Amelie and Archie hadn’t been able to visit the U.S. for over two years due to COVID restrictions, Anstead shares, making the visit extra special for the teens.

“There were a lot of big firsts for them,” the father of three says of the kids' three-week-long trip. “New house, seeing Hudson, meeting Ren… It was great.”

Ahead of the visit,Anstead told PEOPLEthat “Hudson was just 12 weeks old the last time Amelie and Archie got to see him in person. Then COVID hit and the borders shut down.” Now, he says, the reunion was everything he could have asked for.

“It was the sweetest reunion, because I’ve been so consistent with making sure that we always FaceTime, always text, always talk, always Zoom, that when Hudson, Amelie and Archie were reunited they already knew each other,” Anstead explains. “It was really interesting to see how technology had kept us together. But because my fear is, gosh, as a little boy, his world exists within the bubble we create. And it really, really was amazing.”
