Kate Beckinsale didn’t let her 50th birthday pass by quietly as she through the mother of all parties to celebrate her milestone.

The Underworld actor was glammed up to the nines in two stunning outfits for the occasion, including a high-neck bejewelled bodysuit accompanied by a plush feather boa and statement black bow in her hair.

She also wore a stunning red velvet halterneck gown with glittering embellishments as she posed alongside her celebrity attendees.

Posting a slew of pictures to her Instagram page, Kate cuddled up to Hollywood icon Demi Moore, Heathers’ Brendan Scannell, Foursome actor Rickey Thompson, and The Only Way Is Essex star Vas Morgan.

Other attendees included Selling Sunset’s Chelsea Lazkani, costume designer Gabriella Morpeth, Rebel Wilson’s fiance and Lemon Limon founder Ramona Agruma, Jane Doe Latex owner Nina Kate, rapper Big Boss Vette, and influencer Lilah Gibney.

Vas can be seen presenting Kate with not one, not two, but five different birthday cakes before the birthday girl enjoyed a boogey alongside her pals to celebrate the milestone.

It was just one of the many celebrations for the star after she enjoyed a pink-hued Barbie and PlayBoy-themed party that began at her house before the guests went out for a spot of karaoke, including Kate’s mum Judy Loe.

Kate looked incredible dressed as an iconic Playboy bunny in a glittering black leotard, sky-high heels, and bunny ear headband.

In a caption on one of her celebratory posts, she said getting older is ‘f*****g great’ and praised her loved ones for welcoming her 50th trip around the sun.

‘I tell you what. Getting old is f*****g great. Thank you from the bottom of my heart for the most magical day full of joy and love and dear dear friends and the odd bird (not me but also me),’ she wrote.

It comes after a tough few weeks for the star after the death of her beloved cat Clive.

Sharing the news of her loss alongside a photo of her cuddling the feline, she wrote: ‘Clive has died. I don’t have it in me to make a montage or even look at pictures of him yet.

‘Every single part of my house feels like he should be in it. If anyone is expecting to hear from me, you may not for a bit and I’m sorry. My heart is absolutely and totally broken.’

In April, she opened up on how cat-fishers tricked people into turning up at her house during lockdown.

In an Instagram post, she revealed that multiple men attempted to enter her home over the lockdown period as they genuinely believed they were in a relationship with her.

Just over a week before, Kate said she was recovering from a mystery illness that had seen her hospitalised.
