Jenny Slate and Jon Hamm [1] may or may not be dating, and the internet is having a field day. The pair, who costarred in Aardvark earlier this year, were spotted catching a movie together. While it could just be a friendly outing, both of them are newly single. Jon recently had a "really hard" breakup [2] with his girlfriend of 18 years, Jennifer Westfeldt; meanwhile, Jenny famously split from her Gifted costar [3] Chris Evans in February. Even though the actress kept their relationship under the radar [4] when they were dating, she was practically an open book during her interview with Vulture, adding that they were just "really, really different" in the end [5]. Perhaps she's found love with another costar [6]?
