Later sharing photos from the same night, Anstead called his kids "Absolute utter LEGENDS."

The couple, who met on the set of his show Celebrity IOU: Joyride in Spring 2021, have been living together in Laguna Beach, California.

"Ant is very happy with Renée. He really loves her," an entertainment source told PEOPLE in March, adding that the British car expert could be leaning towards proposing soon, but "Ant doesn't want to rush things."

The pair also enjoy spending quality time with Anstead's 3-year-old son, Hudson — whom he shares with ex-wife Christina Hall — at the beachfront home.

Despite maintaining busy schedules, both Anstead and Zellweger "very much prioritize Hudson," the source told PEOPLE. "They want him to be happy and comfortable."
