Jennifer Lopez's children often crash her workouts.

Tracy told PEOPLE: "She's such an awesome mom. That's the thing I love about her, her kids will run into the session at any time.

"Emme is so sweet, she doesn't interrupt, she just watches and twirls. But Max is full of energy."

And despite their young age, Tracy predicts Max and Emme are talented enough to follow Jennifer and their father Marc Anthony into showbusiness.

She said: "Let's put it this way, they're both going to have tons of options. They're both clearly talented and beautiful kids already, for sure."

Jennifer Lopez recently admitted she feels mom guilt when she gets lost in her work and hates to be away from her kids for too long.

She said: "If I get lost in my work for a little while I feel guilty. I feel so guilty when I come out of that haze. Like, 'Oh God, it's been seven hours and I haven't even checked on them. What is wrong with me? What kind of mother are you?'"

But the 46-year-old singer and actress does her best to try and alter her schedule to fit in with the kids.

She added: "It's having good people to help you take care of those kids. My kids visit me at the set [of her new television show 'Shades of Blue']. They have a room on the set so after school they come right there.

"I try to shoot this show in the summer so it's only a couple of months that I'm doing the show when they're in school. We work it out and have a life and this is their life."
