Speaking to Digital Spy, the One Show presenter - who finished fifth in the 2011 series of Strictly - said that people should "bow down" to the 84-year-old light entertainment legend, rather than try to force him out.
"[Bruce has] done a brilliant job," Jones said. "It'll be a sad day when he steps down. It won't be the same without him.
"I know lots of people have got varying opinions [on him and Tess Daly presenting], but actually if you picture it without them it would be a very different show I think.
"People are already kind of speculating who will take Bruce's place and I just think, 'Oh, love him. He's still there'. He's really good at his job so let's just let him be."
However, Jones did say that if Forsyth ever chose to leave Strictly, she would replace him as host "without even thinking about it".
"I think it's the best show on TV," she said. "The experience of being on it was like a brilliant dream. Yeah, of course [I'd do it], of course, but I would rather Bruce stayed."
Jones added that she is now able to empathise with Let's Dance for Comic Relief contestants, as she felt like she was going to "projectile vomit on the audience" every week she was on Strictly.
"These people taking part are brave," she said. "I know what it's like to dance on a large show on a Saturday night. It's the most terrifying thing in the world.
"I thought I was going to just either collapse because my heart would start beating way too fast or projectile vomit on the audience. It's just an awful experience... nerve-wracking."
EastEnders actress Natalie Cassidy, Not Going Out star Tim Vine, boxer Ricky Hatton, comic Nina Conti and impressionist Jon Culshaw have been confirmed as the first celebrities taking part in the new series of Let's Dance for Comic Relief, which begins Saturday, February 16 at 6.50pm on BBC One.
