The rumored couple were first seen together in September at Walt Disney World.
The pair – who were first linked in September – continue to fuel romance rumors as they were spotted enjoying a candlelit dinner together at Pace restaurant in Los Angeles on Wednesday.
Hudson, 36, and Jonas, 23, “were seated at a corner table on the outdoor patio for four hours,” according to Entertainment Tonight. “They were among the last patrons to leave the restaurant just after midnight, and were then seen leaving together in a limo SUV.”
“[Kate and Nick] stopped talking for a little bit just because they were sort of in different mindsets, but that happened for only a few weeks,” a source told PEOPLE about the duo reconnecting.
“[The] age gap is a little bit of a concern,” explained the source. “There’s definitely an attraction there, and they’re just trying to figure out how to make sense of the situation.”
Jonas recently spoke highly of Hudson in his Complex interview, calling the actress “amazing” and even admitting that he and Hudson are “a bizarre match-up to a lot of people.”
“Kate’s incredible,” he said in the February/March cover story also adding, “We had an unbelievable connection as two humans who just admire things about each other, and see something in each other that’s beautiful.”
In January, the two were spotted on a getaway at California ski resort Mammoth Mountain.
