“The powers that be won’t let us spill just yet…”

OG Charmed star Holly Marie Combs has left fans in meltdown mode… AGAIN.

The American actress – who played Piper Halliwell on the critically-acclaimed fantasy drama from 1998-2006 – tweeted yesterday (4 September): “The powers that be won’t let us spill just yet but … I can say I’m playing my sister’s sister. So there.”

Fans were quick to assume that the much-speculated Charmed comeback was in full force, with one fan responding: “I’ve waited 15 years for this I’ll take it! I’m ready and waiting to stan the fuck outta this. Welcome back baby.”

Another wrote: “We’re about to have a heart attack from your hints, dear Holly!”

It comes just a week after the star reunited with her on-screen sister Alyssa Milano (Phoebe Halliwell) and two weeks after she cancelled an appearance at Wizard World Sacramento and said Charmed fans “will not be mad at what’s to come”.

All of Holly’s tweets have had fans freaking the fuck out; last year when the star was asked if a ninth season with the original cast was possible, she replied: “A whole season? I don’t know if a whole season, but maybe something.”

She was then questioned if a movie was possible, to which she said: “Possibly. I say never say never.” Brian Krause – who played Leo Wyatt on the series – agreed with Holly and claimed it’s “possible”.

Some fans have come to the conclusion that Holly will in fact be playing Alyssa’s sister in her controversial Netflix series Insatiable for its upcoming second season, which makes a bit more sense than a Charmed comeback.

Airing for eight seasons, the series focused on the most powerful witches in the world who use their combined “Power of Three” to vanquish demons, warlocks, all evil-dwellers, etc, all while maintaining their personal and professional lives.

It also starred Shannen Doherty as Prue Halliwell, the third and oldest sister who was controversially killed in the season three finale. She was replaced with Rose McGowan’s character Paige Matthews, who later completed the Power of Three.

At 178 episodes, the show became the longest running hour-long television series featuring all female leads (until it was surpassed by Desperate Housewives in 2012) and the second-longest drama broadcast by The WB network.

The show developed a cult following, and is often described by critics as one of the most influential television shows of all time.

Because of its critical acclaim (and because it was the second most streamed show of 2012, six years after the finale), Charmed received a reboot by The CW, which aired its first episode on 14 October 2018.
