Tony and Ziva (Michael Weatherly and Cote de Pablo), NCIS
Yeah, yeah, we know all about Gibbs' "never date a co-worker" rule, but seven seasons of unresolved sexual tension is enough, isn't it? The pair has been in a number of tight spots over the years, but their chemistry has never been more palpable than when they were stuck in an elevator in the Season 10 premiere. We hope one of the things they discussed was taking their relationship to the next level this year.
