I guess it’s like they say - there’s no such thing as bad publicity.

Those curious to see LeAnn Rimes and Eddie Cibrian’s on-screen action (we’ve already seen the off-screen version), gave Lifetime its best numbers of the year. Saturday’s premiere of Northern Lights, an adaptation of a Nora Roberts novel, was watched by approximately 4.5 million voyeurs. That’s the largest audience the cable channel has seen for one of its movies in 2009.

According to Us Weekly, the costars - both married - have been engaging in an affair since filming the project last fall. Although Cibrian has denied any wrongdoing, the country singer has only said that this is a “difficult time” for her and her loved ones.
