Seemingly in town for the holidays, Hudson and Bellamy were spotted out and about doing some last-minute holiday shopping at hotspot Boogie’s Monday evening.

“They were extremely happy,” an onlooker tells PEOPLE, adding they were in good spirits and looked “just really friendly.”

There was no PDA, but “they stayed together. He carried her bags for her,” the onlooker says. “They were laughing and smiling together.”

Hudson, 35, and the Muse frontman, 36 – who have a son, Bingham Hawn Bellamy, 3 ½) – called off their engagement earlier in December, PEOPLE exclusively confirmed. “Kate and Matt have been separated for some time now,” Hudson’s rep said at the time. “Despite this, they remain very close friends and committed co-parents.”

Soon after announcing the split, Bellamy took to Twitter, posting: “We’re both very happy, it’s for the best.”

The rocker proposed to actress Hudson in 2011 after dating for about a year.
