.: Charmed to bewitch their fans :.

Eight years since its last episode went to air, the stars of hit US supernatural drama Charmed admit they are surprised by how much love fans still have for the show.

In Perth for the first time to appear at Oz Comic-Con at the Perth Convention and Exhibition Centre this weekend, Holly Marie Combs and Brian Krause were among the longest-serving characters on the critically acclaimed series, which ran for eight seasons from 1998-2006 and amassed a staggering following across the globe that lives on well after the series ended.

Combs, who played witch Piper Halliwell in the show, and Krause, known for his role as white-lighter Leo Wyatt, regularly catch up at conventions around the world - they just returned from Paris - and say they love to hear about the personal attachments so many fans have with Charmed.

"It's impressive and endearing to know that people still enjoy it and it's still timely for people," Combs told AAA Weekend.

Another perk of sci-fi conventions is the chance to travel around the world - with the two stars set to jet off to Germany and Italy for similar events in coming months.

From marriage proposals to tears and lingering embraces, Combs and Krause have seen it all when it comes to besotted fans and say celebrity signature tattoos are fast becoming a new alternative to plain old autographs.

"We have already been told there is a man (in Perth) who has a tattoo of the spell book coming out of his skin and he wants us to sign his leg so he can get it tattooed," Combs said.

Krause added: "It's a trend these days, which is kind of sad because I haven't done it."

"You haven't yet? You will," Combs, who currently stars in smash-hit teen drama Pretty Little Liars, laughed.

As for rumours there are plans by TV executives to remake Charmed with a whole new cast, both actors did not seem keen on the idea, saying it might "confuse" fans.

"I think it is too soon. I think Charmed fans might not accept the new show," Krause explained.

"But you never know. I think the best idea would be to make a movie but it's not up to us."
