It may be cold outside, but Mariah Carey and Nick Cannon are superhot in matching red parkas during a visit to Aspen, Colo., on Dec. 23, 2008. Even in the early stages of their relationship (the couple met earlier that year), they coordinated looks. Mariah dressed like ex-boyfriend Eminem in the music video for her song "Obsessed," a dis track that fueled the flames of their feud, but we're pretty sure Mimi wasn't rushing to adopt Em's trademark T-shirt and hoodie style anytime soon. Maybe that's why it didn't work out? For Mariah, compatibility is about more than chemistry!
