Alert – Alex Scott and her ‘girlfriend’ Jess Glynne show off their Halloween looks as they make latest joint appearance at the Haunted House of Friends party

Alex Scott and Jess Glynne led the arrivals at the Haunted House of Friends Halloween party presented by Casamigos Tequila in London on Tuesday.

The rumoured couple were first claimed to be in a secret relationship last month and the party at The Twenty Two marked the latest time they’ve been seen together.

The TV presenter, 39, and the singer, 34, posed separately on the red carpet as they arrived at the star-studded bash alongside Lottie Moss and Nick Grimshaw.

Alex put on a showstopping display in her costume, which featured a metal bralet and dramatic headpiece, along with a thigh-lit skirt.

The former footballer added a pair of coloured eye contacts and a pair of vampire fangs to the ensemble. 

Before heading to the party, Alex posted a picture of her costume to her Instagram Story, telling fans: ‘If you know, then you know!’

Meanwhile, Jess oozed sex appeal in a skintight black latex dress, which hugged her slim figure as she smouldered for the camera.

The Hold My Hand singer wore her flame-hued locks in a loose sleek style, while she opted for Gothic make-up with red contact lenses.

Jess channelled Morticia Adams on the night out, as she joined her rumoured love interest Alex at the star-studded bash.

Jess and Alex were pictured together for the first time on October 25, since their ‘secret relationship’ came to light.

They were seen getting out of a taxi as they arrived at The Hawley Arms in Camden, north London, for an intimate gig to celebrate Jess’ new single, Friend Of Mine.

The joint appearance came after it was reported that the pair have been in a secret relationship with each other for the past few months.

On Jess and Alex’s ‘relationship’, a friend told The Sun: ‘Alex and Jess have been a slow burn and they didn’t want to rush things or go public too soon.

‘But they’re officially an item now and seem really happy. They are both strong, independent women with a shared passion and respect of their respective careers, supporting one another from the sidelines.

‘It’s still early days for them, but they’ve met one another’s mates and everyone is super happy for them.’

Also at the party was Celebs Go Dating star Lottie Moss, who took racy to new levels in bondage-inspired gear as she arrived at the event.

Lottie sported nipple covers and a chain bra, while also sporting a pair of fishnet stockings with towering heeled boots.

The sister of Kate Moss, who was carrying a whip in her hand, wore her blonde locks in a ponytail and opted for a glamorous coat of make-up.
