LeAnn Rimes Channels Sports Illustrated Swimsuit Cover

The singer captioned the revealing pic: "Models in training @SInow sequel #happymemorialdayboys #wetryhard #having fun."

Clearly the bikini goddesses were having a good time: the 31-year-old blond beauty put those pregnancy rumours to rest by sporting a pink two-piece while her two friends sported colourful swimsuits that showed off their butts and then some.

But that didn't stop LeAnn from joking with a fan that she was with child. When a Twitter user mentioned the size of the singer's breasts, LeAnn joked, "im producing milk lol."

Pregnant or not, it can't be denied that Eddie Cibrian's wife looks amazing!
