Looking good (and more importantly, doing good) is the best revenge. Just ask LeAnn Rimes!

Eddie Cibrian's wife dazzled Thursday at the 2013 ChalleNGe Champions Gala in Washington, D.C. Wearing a sexy, semisheer black Isabel Marant dress and thigh-high Roland Mouret boots, the 30-year-old country star happily posed alongside the cadets.

The event helps raise money so that the National Guard can give high school dropouts the chance to earn a diploma or their GED, improve their self-confidence and equip them with skills to prepare them for the workplace or continuing their education. LeAnn, a frequent supporter of youth initiatives, was excited to come out for such a great cause.

Of course, that's not all the blond beauty's been up to this week. On Sunday, LeAnn attended the 2013 Oscars with Eddie. Also in attendance? Brandi Glanville, whose tell-all book Drinking & Tweeting: And Other Brandi Blunders portrays her former husband and LeAnn in a very harsh light.

But LeAnn didn't let a potentially awkward situation dampen her evening. She tweeted several smiley pics of herself and Eddie throughout the night and appeared to enjoy herself.

Positivity FTW!
