Jennifer Lopez is fit and fabulous at 43, thanks to her longtime dedication to a healthy lifestyle.
"I never drank or smoked, and it's really paying off now because my skin is still really good with moisturizing and getting good sleep," Lopez told People Jan. 16. "I've never had Botox or any of those things. But when I need to, maybe I will."
Jennifer also follows a healthy, portion-controlled diet, limits sugar and salt intake, gets enough rest and works out regularly. She hasn't had any plastic surgery or Botox yet, but is open to both down the line.
"I don't know how I'm going to feel [a few years from now]," says the divorced mother of two. "I reserve the right not to know right now, and I don't judge anybody who does it."
While Lopez feels and looks great, she feels insecure about dating a guy 18 years younger than she is.
"'I ask him, 'Why don’t you go find a young girlfriend and get out of here? What do you want with me?' " she says of her back-up dancer boyfriend, Casper Smart, 25.
"And you think, 'How long is this gonna be?' You think, 'Okay, in 10 years I’m going to be like this and you’re going to be like that.' "
Jennifer credits Casper with helping her heal during her difficult divorce from singer Marc Anthony (the couple split in July 2011 after seven years of marriage). Lopez and Smart began dating in October 2011. While she worries about the toll aging will take on her and on her relationship, she's happy now.
"The truth is we don’t know what’s going to happen," she says. "We’re loving this moment right now. We make each other happy."
