London, Nov 5  : Rocker Rod Stewart is sacrificing sex these days, because wife Penny Lancaster is too exhausted after her Strictly Come Dancing routines.

Penny recently revealed that any energy she has left after practice sessions is used up looking after their two-year-old son Alastair.

 “Rod understands all in all, but the show is a passion killer,” The Sun quoted her, as saying.

“There’s looking after my son as well as doing all the rehearsals and I’m really exhausted, to be honest,” she added.

The 36-year-old is so devoted to the BBC1 show that she even takes dance partner Ian Waite to lunches and dinners with Rod.

 “Our household used to be all about free kicks, passes and football. Now it’s paso dobles and foxtrots,” Rod said. (ANI)
