The former Brookside actress - who has reportedly lost five stone since having her little boy, Bobby - says work means life is a juggling act.
Jennifer says the skating practice and work commitments in the run up to the live Dancing on Ice shows left her with little time for her son, who turns two next month.
She told this week's new! magazine:
"It has been a huge juggling act for me. For the first eight weeks of training, I was on tour with Calendar Girls. Because I was moving around, I had a different coach at a different ice rink each week.
"I was also doing eight stage shows a week and still trying to be a mum. Some days, I'd travel four hours to an ice rink, then go home, kiss Bobby and then go to Calendar Girls."
Jennifer, 28, says that as a toddler, Bobby cannot understand why mummy has to leave him:
"He's too young to understand that I have to go to work, earn a living. That's when I feel the guilt."
The hard-working mum revealed that she had 'a bit of a cry' when she had to leave him in Liverpool for a week recently whilst she trained for Dancing on Ice in London - but found modern technology saved the day!
"I had a bit of a cry leaving him because I'm not going to see him until the weekend," she says. "But, luckily, I can Skype him every night!"
