'Stranger Things' actor David Harbour may be dating 'Fantastic Beasts and Where to Find Them' star Allison Sudol. The 42-year-old actor was spotted leaving the BAFTA Tea Party with the 33-year-old Sudol on January 6 in Los Angeles. An onlooker says, ?They left arm in arm. Alison was teasing and joking with him. They seemed very much like a couple.? A day later, the pair arrived at the Golden Globe Awards in the same vehicle. Harbour and Sudol reportedly sat together during the show and both attended the Netflix afterparty.
