Getchya popcorn ready for the biggest boxing match in women's history ... 'cause Cecilia Braekhus tells TMZ Sports she's down for a superfight with Claressa Shields!!!
"I wanna be in a ring with that," Braekhus says.
Of course, Cecilia and Claressa are considered the two best female boxers on the planet -- Cecilia is 35-0 while Claressa is 9-0 -- and Cecilia says she's willing to duke it out in the ring to see who's No. 1.
The only problem??? The two are in totally different weight classes -- Claressa has about 13 pounds on Cecilia -- but Braekhus tells us she'll come up in weight if Claressa will go down.
