Jenny Slate and Jon Hamm 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 with his girlfriend of 18 years, Jennifer Westfeldt; meanwhile, Jenny famously split from her Gifted costar Chris Evans in February. Even though the actress kept their relationship under the radar 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. Perhaps she's found love with another costar?
