She's the voice of one of the most successful duos in country music history and a mentor on the hit TV show "Duets," all while juggling a calendar full of cross-country tour dates ... And that's on top of planning for her first child! But Sugarland's Jennifer Nettles assures she's no different than any other hormonal pregnant lady.

"I crave Mexican food, which [Los Angeles] has been the perfect place for that," Jennifer tells the morning television show, "Good Day LA." "Anything salsa, spicy, I love that. Anything vinegar-y or tart, I love that. Fish tacos ... I'm pretty much a free-for-all at this point. [laughs]"

One big surprise for the mama-to-be has been her lack of desire for sugar. "It's not my main craving, which is interesting, because I normally have a big sweet tooth," she admitted.

While juggling her career and personal life has gotten easier over the past few months, Jennifer went through a rough patch. "The first three months were a challenge, because we weren't telling anyone and we were still working," she recalls. "I cried all the time. I cried on the show. I begged the producers, I was like, 'Please don't make me that girl.' And they didn't know why, obviously. I mean, I am sensitive, but not that -- I mean, I would cry at Olympics commercials and ridiculous things."

In late November, Jennifer and husband Justin Miller will celebrate their first wedding anniversary, right in time for the arrival of their baby. Certain changes in lifestyle are inevitable when two become three, but don't expect this mama to give up on her fans.

"When baby comes, we'll definitely have to do something [about the tour bus]," she says, adding, "I don't know exactly when but I will be touring, because I love it so much."

Jennifer is still in the City of Angels, as the season finale of "Duets" airs tonight (July 19). The songstress is back on the road with a Sugarland tour stop in Harrington, Del., on Saturday (July 21).
