Who saw this May-December pair coming?!

Kate Hudson, 36, and Nick Jonas, 23, were spotted together multiple times over the weekend, and the two "have definitely hooked up," TMZ reports.

The Almost Famous actress certainly appeared to be in a good mood when the two were spotted by fans at Walt Disney World in Orlando, Florida on Saturday.

Hudson also attended the "Jealous" singer's House of Blues show that night, TMZ reports, and the next morning, the pair was spotted having brunch in Miami. The Mother's Day star was comfortable enough to go makeup-free, with both of them going super casual in matching white t-shirts.

Clearly, Hudson is at least a fan of Jonas' music. She was spotted attending his concert in New York City on Sept. 10.

Although the two reportedly aren't actually dating, this wouldn't mark the first romance Jonas has had with an older woman. In 2011, he dated Australian singer Delta Goodrem for over a year, when he was 18 years old, and she was 26. He was most recently linked to 19-year-old Kendall Jenner, after splitting with former Miss Universe Olivia Culpo in June.

Meanwhile, Hudson called it quits with ex-fiance Matt Bellamy last December, and was later linked to 30-year-old Dancing With the Stars champ, Derek Hough, when the two showed some PDA at a U2 concert in Los Angeles in May.

ET caught up with Jonas in June, when the Scream Queens star said he's currently focused solely on his work. "I'm doing OK," Jonas told ET about his breakup with Culpo after two years together. "But it's always hard and my thing now is focusing on my work and staying as busy as I can, as creative as I can be. These are the times you’ve just got to dive in and get lost in your work and that's what I'm trying to do."
