The Florida lovebirds met in 2011 and are getting hitched next year – after each changed genders. Muscle-bound Mark was born a girl with wavy brown hair and a pretty smile called Maritza Perdomo, while blonde Jessica was once a tow-headed boy named Shawn O’Donnell.

But Mark, 49, a dedicated weightlifter and occupational therapist, transitioned in 2003 and is now legally recognized as a man.

And Jessica, 39, underwent an operation to remove her testicles earlier this year and is now officially a woman who is already using her future hubby’s surname.

The unlikely couple said it was love at first sight.
