Rimes Caught Kissing Another Man ... Her Hubby

LeAnn Rimes went into full-on damage control mode today, sucking face with her husband Dean Sheremet in public.

Of course, it's only been a few days since some scandalous footage hit the web, allegedly showing Rimes kissing her really hot Lifetime movie co-star Eddie Cibrian.

LeAnn and Dean have been married for seven years.
