Playing a divorced woman who falls for a younger man in "The Boy Next Door," Jennifer Lopez has recently talked about how she maintained a toned physique at the age of 45 and said she owed nothing to plastic surgery.

"I haven't done anything," Lopez told People. "I don't know how I'll feel in 10 or 15 years. I deserve the right to feel how I feel at the time. This person doesn't feel the need to do anything."

To prepare for her role in "The Box Next Door," in which she had a sexy scene with her co-star Ryan Guzman, 27, Lopez said she went back to the basics, which is to eat right and exercise and "put in the work like everyone else."

Lopez also said her regime includes cardio, circuit training and workouts by celebrity trainer Tracy Anderson. According to the "American Idol 2015" judge, it is necessary to switch it up to "keep your body and yourself fresh."

Claiming that she has never gone under the knife, Lopez said she absolutely feels comfortable in her own skin.

In another interview with HuffPost Live, Lopez talked about her life a decade ago. She said the worst and lowest point was the time when she and former boyfriend Ben Affleck starred in "Gigli," which described as a "very badly reviewed" movie.

At the time, Lopez said she was in a high-profile relationship that "fell apart in a really bad way" with the weekly stories in the magazines talking about how her life was falling apart.
