LeAnn Rimes wants the world to know she's serious about new husband Eddie Cibrian. The 'Blue' hitmaker was spotted out and about at Lollapalooza in Chicago this weekend with her man, in a tattoo booth of all places. Rimes spilled that she's getting a line from their wedding vows inked on her body somewhere.

The country singer, who is splitting her time between L.A. and Chicago -- where Cibrian is filming 'The Playboy Club' -- wasn't in the tattoo shop to actually get the tattoo just yet. Rather, she was sampling different spots on her body where she could potentially profess her love. She revealed that her tattoo will say, "You gave me the courage to be truthful, I promise to give you the comfort to be trustful," which is a line from the vows that Cibrian said to her during their wedding ceremony on April 22.

From there, sporting a new tattoo stencil on her right ribcage (see the picture here), Rimes and Cibrian bounced around the Express Yourself Oasis in the Hard Rock Hotel, where they reportedly enjoyed UV vodka drinks and scoped out a Motorola XOOM.
