LeAnn Rimes candidly reacted to fans who questioned whether she got a boob job for her role as Dixie on ABC's new hit series 9-1-1: Nashville. During an Instagram Q&A on Sunday, November 9, Rimes, 43, poked fun at a comment she received, which just read, "boob job." "If you are referring to my boobs, I can't believe I am talking about my boobs," she quipped. "But if you are referring to my boobs in some of the videos that I have been posting when it comes to my character in 9-1-1: Nashville, I have the most massive push-up bra of life on." Rimes clarified that she didn't have any procedures. "In fact, when I took off the bra one day, my boobs stayed up by my chin a bit before they fell," she joked. "So no, I did not get a boob job. Nothing that has not been there already."

Disney/Jake Giles Netter Rimes loved the campiness that comes with 9-1-1: Nashville. "If you think about it - in the world of however many millions of people there are - this stuff is bound to happen to somebody. Every time we think it hasn't really happened, there's an article for that that shows you it has," she noted. "What I love about it is once you buy into the craziness of this show, you just fall in love with it." She continued: "I remember watching the first couple episodes of 9-1-1. I was like, 'What am I watching?' And then about the third episode, I was like, 'Whoa, I'm totally into their own reality.' You just fall in love with it." During her recent cover story with Us, Rimes teased how divisive her role would be, saying, "I think people will love to hate her - and they'll really love her too.

"For my audition scene, Dixie smokes and so I went and bought a pack of cigarettes. I sat around the house and - without lighting it since I've never smoked in my life - I was messing with the cigarette. I took them to the audition and I was like, 'I'm gonna use these.'" Rimes continued: "My hand was so shaking at the very first read and once I got through with that, I was like, 'OK, can we do it again? Like, now that I've gotten through it.' I wasn't even home yet before they called and offered me the job." 9-1-1: Nashville airs on ABC Thursdays at 9 p.m. ET before streaming the next day on Hulu.
