ET recently caught up with legendary rock icon Rod Stewart to talk about his two-year Caesars Palace Las Vegas residency, which is set to begin August 24. The 66-year-old revealed how he stays in tip top shape in order to continuously perform his state of the art concert "Rod Stewart: The Hits", which turns out to be a combination of good old fashion exercise and being around his eight children."I work at it. I work in the gym four or five times a week, which I’ve done for 12 or 13 years now," Stewart says. "I still play football…and [being] surrounded by all my children I'm sure has something to do with it," he quips.No doubt use to sell-out crowds and performing in every type of arena there is, Stewart shared how much he appreciated the intimacy of his Las Vegas concert venue, The Colosseum at Caesars Palace.
