Filming for next years Gilmore Girls revival is already underway, but one cast member's presence has yet to be confirmed – Melissa McCarthy.

Although Lauren Graham (Lorelai), Alexis Bledel (Rory), Scott Patterson (Luke) and a whole host of others are already on board for the four-part reunion, there's been a lot of back-and-forth about Melissa's participation on the show.

Now Melissa has revealed that she most likely won't be reviving her role as Sookie – though she insists there's no bad blood and that it was simply a matter of scheduling.

"I don't think I am [coming back]," she told E! News this week while promoting her new film, The Boss.

"I didn't actually get asked to do it. But I think they thought I was busy, and then by the time it did come up, then I actually was."

Though she won't feature in the revival, Melissa promised that she'd be tuning in with the rest of the fans.

"I loved that show, and I think the fans for that show are super loyal and great and I will watch every single one of them." 

With both Ghostbusters and The Boss coming out this year, it's no surprise that Melissa might have less time on her hands than her former co-stars, but we're still holding out hope for a cameo.

But despite Melissa's reservations, Gilmore Girls creator Amy Sherman-Palladino admitted she'd happily write in a last-minute part if it came down to it.

"Look, if Melissa is available and has an afternoon free, I'll write her a scene," she said last year.

"Melissa was one of us. If she has a spare moment to run over [to the set] — even if for just a cameo — we would be totally game."

Fingers crossed.
