Having just returned from the 2011 Grammy Awards, LeAnn Rimes has her sights set on planning her upcoming wedding and getting married -- and she has just found a much needed element: her wedding dress.

When asked which designer will have the honor of dressing her on the big day, the 'Swingin'' country star admits, "I'm keeping it secret." Last time she was married she chose a favorite designer of hers, Vera Wang.

Rimes has been engaged since last December to former 'CSI' star Eddie Cibrian and is sporting a 5-carat engagement ring. The singer tells PEOPLE she's planning her wedding right now and says,“It's [going] well. It's an exciting year and a lot to handle, but I've got a good man at my side. So he's helping!"

Even though she is currently finishing two albums and looking into some new acting roles, Rimes says, “I feel like I have a lot going on, but it’s kind of chill. We’re taking it as it comes and planning as it comes."

She adds, "I’m looking forward to settling down, settling into our life. He [Cibrian] really is the sweetest, most supportive man."
