TV star Denise Drysdale is causing top executives plenty of excitement as they believe she is a “saviour” to their prayers.

Their praise comes after the panel show Studio 10 had a massive boost in ratings when she appeared on it recently.

"Studio 10 has had an axe looming over it, and Ten were in complete panic mode a few weeks back when the show's ratings dipped to a worrying low of 33,000.

But the next day, execs heavily promoted Denise on the show and there was a huge spike of 10,000 viewers," says the insider to Now to Love.

The insider says that Drysdale’s ratings boost hasn’t gone unnoticed by top executives, but they’re worried that she will leave as she regularly talks about loving her simple life on the Gold Coast.

"She already gets $5000 a week for two or three episodes, but Ten are well aware that Denise could start demanding even more money," says the insider.

"If she did, it would have to come from somewhere and that means someone else's salary."

But a spokesperson for Ten has confirmed that there will be no changes to the current panel line-up.

"At this stage, there are no plans to change the panel," they said.
