This weekend will see the 84-year-old take a break from the show and replaced by Claudia Winkleman, but it's not a sign of the Beeb looking to replace him.
"The BBC knows he’s an asset. You’ve got to respect someone who’s been in our living rooms for most of our lifetimes. They accept that and treat him accordingly," Tess told the Daily Mail today.
She continued: "Sure, he’s 84 but, boy, he doesn’t act it.
"If you have a conversation with Bruce, age isn’t even an issue because he is so fully present. He has that mischievous, wicked glint in his eye.
"He’s always looking for the gag, he’s always dancing, he won’t stay still. I just think he’s phenomenal really."
Sir Bruce himself insisted he has no plans to quit yet, with Tess adding: "We’re good friends, we trust each other. We can almost finish each other’s sentences."
This week Strictly Come Dancing is on Saturday 10th November at 6.30pm with the results show on Sunday 11th November at 7.25pm on BBC One and BBC One HD.
