The broadcaster, 62, puts on the bash in his sprawling family home in leafy Hampstead, London, where star-studded guests dress up in their best spooky outfits.
For two years the party was cancelled – in 2020 due to the Covid pandemic and the following year because his daughter Betty, 32, was struggling with fibromyalgia – but it came back with a bang last October.
However, it was held at Camden nightspot KOKO for the first time instead of Ross’s famous home last year, but has now returned to his family home for the first time in three years.
Preparations were underway once again as enormous pumpkins were seen being carried onto the patio, while various ghoulish structures – including what looked to be a massive forbidding gate – were assembled.

In addition, giant stone walls were carried into the ground to build a fairytale-esque castle with turrets.
Last year, Spice Girl Mel C went as Morticia Adams, while Rita dressed up as a very scantily-clad Lisle Von Rhuman from Death Becomes Her.
After the party was cancelled for the first time in 2020 due to Covid restrictions, the broadcaster, 62, called it off for a second time the following year for a personal and emotional reason.
The comedian cancelled for a second time after his daughter Betty was diagnosed with fibromyalgia, a long-term disorder characterised by chronic muscle pain.
Betty also has chronic fatigue syndrome and postural tachycardia syndrome (POTS) which causes an abnormal increase in the heart rate after sitting or standing.
Confirming his decision to cancel for the sake of his daughter in 2021, he told Good Morning Britain: ‘One of our children isn’t well… it’s fibromyalgia which is quite debilitating. She’s back home with us and we’re looking after her.’
Ross, whose annual bash is normally a staple of the celebrity calendar, explained that he didn’t feel comfortable throwing the party while she is struggling with the condition and feared any of his guests falling ill from Covid after attending the party, and so decided to cancel the event.
He said: ‘I had a feeling it wasn’t going to be over yet and it does look like the figures are creeping up again. We always have a couple of hundred people to the party and as you know, about half of them are from show business.

‘So if there was a breakout would wipe out half the shows on TV, so we don’t want that, we wouldn’t want to be a superspreader event.’
‘She’s upstairs in the bedroom and I thought, ‘I can’t in good conscience have a big loud fun party downstairs and one of my children is locked in a room upstairs. It would be like something out of a horror novel.
‘So really, just out of a good conscience, we’re not going to do it, but hopefully next year we’ll be back.’
He added: ‘My daughter, we thought she had Long Covid but discovered that she had fibromyalgia, so we want to be conscious of that and not have so much noise when she’s upstairs.’
The comedian also shares Harvey, 29, and Honey, 26, with wife Jane Goldman, whom he married in 1988.
In July this year Betty said the world had ‘opened up for her’ since getting a new wheelchair.
Taking to Instagram, Betty shared several snaps of herself trying out her new wheelchair from Distribe Limited.
Alongside the photos, she wrote: ‘Since I bought my wheelchair from Distribe just over a year ago, the world has really opened up for me so drastically and so much more than I’d even thought possible before buying.

‘I’ve been able to go out, make memories, and have adventures, even on some of my worse health days.
‘So much of that comes from how confident I feel in the quality of my chair, knowing that it’s not going to give up on me and leave me stranded!
Betty went on to say that using a wheelchair has had a ‘positive impact’ on her life and also described it as ‘liberating’.
She wrote: ‘I’ve said it on my instagram plenty of times already, but truly having a wheelchair has had such a huge positive impact on my life.
‘I feel really hopeful that in this collaboration with Distribe and being able to share my discount code with you all I might be able to play a small part in helping other people to experience the euphoric and liberating change having the right mobility equipment can bring.’
