Pictures first emerged of the singer on her honeymoon in Mexico last week, prompting many to comment that the newlywed looked to have lost her curves.
The 28-year-old, who has just tied the knot to beau Eddie Cibrian, responded by posting two bikini snaps on her Twitter page - along with the comment: "Thx to @MIKOH_SWIMWEAR for another great bikini! Loving wearing them!"
As the pics went live, one follower responded saying that she thought the LeAnn looked "scary skinny," and that there were "a lot of bones showing through skin."
"Those are called abs, not bones love," came LeAnn's response.
Ms Rimes then added: "Thx but this is my body and I can promise you I'm a healthy girl. I'm just lean. Thx for your concern but no need too be."
