Evangeline Lilly dating her Lost co-star Dominic Monaghan is old news, but the couple had a very public breakup a few years back. That’s why more recent sightings of the pair together have raised eyebrows in the celeb gossip community.

Lilly and Monaghan started dating in 2004 after they met on the set of the hit show, but they split in 2007. Still, after the breakup they’ve been spotted together many times in Vancouver, where Evangeline has a home. Hm.

In fact, Just Jared claimed they were still together after snapping a picture of the two in Las Vegas, dining with Dominic’s parents in July 2009.

Our guess? Maybe they are back on, and they’re just trying to keep the lovin’ low-key.
