Sofia Vergara's freezing her eggs

(CNN) -- Sofia Vergara, as we've seen, has a healthy appetite, but these days the actress is paying more attention to what she eats.

The reason behind that, as she told Vogue magazine, is because she's freezing her eggs.

The 40-year-old "Modern Family" star, who's engaged to Nick Loeb, said that she's embarked on a process of hormone pills, to be followed by hormone injections.

"[T]hey want to get as many eggs as they can because usually you produce them but they're not good," Vergara said. "They have to be perfect, perfect, perfect ones. My boyfriend is 37, younger than me, never had kids."

Vergara already has a son, Manolo, from a prior marriage. The 21-year-old happens to be named after Steven Bauer's character in "Scarface," Manny Ribera. "I looooved that movie, and I was in looove with Steven Bauer," Vergara said.

And Manolo is aware that his mom is hoping to have another baby.

"You know, sometimes he used to scream at me when he was younger, 'Why can't you have another baby, so you can stop focusing on me?'" she said, laughing.

If Vergara does become a mom of two, you can bet she'll have the best-tailored maternity wear in Hollywood. The celebrity mogul, who Forbes named the highest-paid actress on TV in 2012, doesn't hesitate to alter an item.

"All the dresses that I wear for the red carpet, I have to build them inside," the curvaceous star said. "I mean, a normal girl will just put the dress on and leave. I need them to be like an armory. My dresses are like a work of art inside because, you know, I am 40 years old, I had a baby, and I am a 32F boob. And they are real, still. When they are fake, you take the bra off and they are still there, perfect! Me - no, so I have to bring them up!"
