Chantelle Cameron will face Mikaela Mayer in a rematch which will serve as the co-main event for Jake Paul's return to the ring in Dubai on Christmas Eve.
The bout comes just four months after Cameron (23-1, 8 KOs) beat Mayer (22-3, 5 KOs) by unanimous decision to become the unified junior middleweight champion, collecting the WBA, WBC and WBO titles.
Cameron, ESPN's No. 2 pound-for-pound fighter, had been in talks to face Claressa Shields -- the undisputed heavyweight and unified middleweight champion as well as ESPN's top pound-for-pound fighter -- but an agreement was not reached.
Paul's Most Valuable Promotions have confirmed the Brit will instead defend her titles against Mayer on Dec. 24.
"I am genuinely excited to box in one of my favourite places," Cameron said.
"I cannot thank Jake, Nakisa [Bidarian] and Mike [Leonardi] for this opportunity to box on a huge show. They promised to keep me active in 2026 and my third fight in nine months proves just that. We agreed to the rematch before the first fight, so we both kept our word, and now the rematch is on the biggest stage in boxing."
Immediately following their first fight, Mayer, who had held the WBC and WBA titles, insisted she won the bout and insinuated Cameron would not have got the result if the fight wasn't in the UK, saying she was "lucky" it was in her "little back yard."
Mayer later apologised for her comments but the post-fight interaction prompted calls for a rematch.
"Mayer vs. Cameron was a great fight that I truly hope everyone enjoyed," Mayer said. "Although I don't feel I performed to my highest potential, I've been working hard to fix the mistakes I made and I will 100% come back stronger! I'm taking my belts back on Thursday, Dec. 24th."
MVP CEO Nakisa Bidarian praised both fighters for taking the rematch so soon after their first bout.
"Chantelle Cameron vs. Mikaela Mayer 2 marks MVP's latest seismic pound-for-pound clash with two of the world's top ten fighters meeting again in their prime," Bidarian said.
"Their first meeting just a few months ago was a clear Fight of the Year contender, and both immediately called for the rematch following the fight -- a testament to both being willing to take on the hardest challenges.
"Now the stakes rise even higher for Chantelle as she puts three titles on the line against a hungry Mayer, one of the sport's biggest faces in her own right and a US Olympian."
American Olympian Jahmal Harvey will look to continue his promising start in the lightweight professional ranks, taking on Scotland's Craig Morgan.
"Christmas will come early as I provide another dominant, eye-catching display under the lights on this Christmas Eve Spectacle. This is not to be missed!" Harvey said.
