Oti Mabuse joined Real Housewives of Dubai star Chanel Ayan at Usher’s sixth sold out O2 show amid his Past Present and Future tour in London on Tuesday evening.

The Dancing On Ice judge, 34, caught the eye as she flashed a glimpse of her ample cleavage in a white cut-out crop top.

Oti’s trendy outfit also showcased her toned midriff and she completed it with a pair of distressed jeans and chunky trainers. 

Elsewhere in the VIP box Chanel, 46, who also appeared in the latest series of The Traitors US, stunned in a figure-hugging black midi dress.

The model sent pulses racing as she went braless and teased a glimpse of side boob while posing up a storm ahead of taking her seat.

Meanwhile on Sunday Usher sent his fans wild as he brought out yet another surprise celebrity guest during his fifth show at the iconic London venue.

The R&B star, 46, is halfway through his string of 10 sold-out shows in the capital as he comes to the end of his worldwide tour.

But rather than winding down, the singer has been pulling out the stops night after night, with his latest gig proving no exception as he invited Estelle to join him onstage.

The British singer and rapper, 45, stepped out to cheers from the audience, looking radiant in a iridescent silver shirt and matching flares.

She swept her braids up into an elegant bun and draped a huge fur coat over her shoulders to matching with Usher, who went shirtless under his.

Estelle then belted out her international hit song American Boy, which she released 17 years ago, and became her most successful single.

The track was a UK number one and featured Kanye West, winning the pair the Grammy Award for Best Rap/Sung Collaboration in 2009.

It marks the latest VIP surprise from Usher at his London gigs, after he previously brought out Naomi Campbell and Craig David.

The supermodel appeared at his show on Tuesday, putting on a very leggy display in a dazzling minidress and strutting down the stage while Usher belted out his hits.

While fellow R&B star Craig delighted fans as he stepped out to sing his hit Fill Me In, before joining Usher for a special duet of his famous song 7 Days. 

Craig said: ‘It was a full-circle moment and such a beautiful thing. Having grown up listening to Usher, from his early work, I was like, wow. “What an incredible voice, what an amazing artist, he has such a unique voice.”

‘So it was such a beautiful moment when I got the call because to have just been performing at the O2 on my arena tour, to then get the call up a few weeks later from Usher – what a way to celebrate the 25th anniversary of Born To Do It, my first album. 

‘I’m such a huge fan of Usher, so it felt like a full-circle moment to have an opportunity to go on stage and perform two of the songs from that first album, which was beautiful.’

Usher will be playing at the O2 for five more nights, before heading to Paris, Abu Dhabi, Amsterdam and Berlin, before arriving back in London to close out his staggering on May 7.

The singer – whose full name is Usher Terry Raymond IV – has been wowing crowds  of around 200,000 people every night with his hits like Yeah, Burn, U Remind Me and OMG.

He’s been showing off his incredible falsetto and enviable dancing skills, with him even donning roller skates during the shows and demonstrating an impeccable moonwalk and handstand.

The hitmaker has also sparked attention on social media for treating some female fans to more up close and personal meetings and seductively hand-feeding them cocktail cherries.

Usher’s pop career is heading into its fourth decade with a head of steam, after the star performed at the Super Bowl LVIII in February 2024 and enjoyed a popular Las Vegas residency last year.

He also wowed US fans with a successful tour of the States but was forced to reschedule his Miami concerts after Florida declared a ‘state of emergency’ amid Hurricane Milton in October.

Though many praised Usher’s commitment to safety for his fans and tour crew, others criticised the decision and voiced frustration over the new dates.
