Leann Rimes claims she has dropped a jean size recently.

The 30-year-old singer, who is married to Eddie Cibrian, has hit back at a report she is pregnant with her first child and insists she has actually lost weight.

The 'Can't Fight The Moonlight' hitmaker wrote on Twitter on Wednesday (10.07.13): ''LMAO Star Magazine! I don't know if you [doctor] the pics or pic the worst one you can find, but I'm far from pregnant & just dropped a jean size.''

LeAnn, who is a stepmother to Eddie's sons Mason, 10, and Jake, six, with his ex-wife Brandi Glanville, previously revealed she would love to have her own child in the future but is in no rush to expand their family.

The 'Spitfire' singer explained: ''We talk about having kids all the time and I would love to, but it's gonna be a second. I'm still young and fertile -- it's all good!

''I was just with the kids for the last two days taking care of them on my own, and trust me . . . I have a newfound respect for working moms who do it all by themselves. It was my birth control for a little bit -- so overwhelming!''
