Strictly Come Dancing 2012 is reportedly putting pressure on Denise's personal life.
According to Star magazine, the West End star has been left exhausted ahead of the live shows later this week.
Denise has been training for three weeks in preparation for Friday's first live performance.
But the rehearsals have left her and husband Lee Mead spending so much time apart, with Lee currently working in panto.
And the couple's young daughter Betsy has had to be looked after by their parents!
"Lee and Denise agreed neither would work at the same time because they didn't want a nanny," a source told the magazine. "But Lee had already singed up for panto when Denise asked to do Strictly and it was too good to turn down.
"Their parents will help out with Betsy, but there could be a real crisis ahead."
The pair, who denied they had split earlier this year, are determined to try and work around each other's hectic schedule.
A pal claimed to the publication: "Denise is already exhausted. It's not ideal that Lee will be away as the contest hots up.
"It's the biggest gig of her career, but it can't be helped, they both need to work."
