Can we walk … down the aisle?

“Fashion Police” chief Melissa Rivers has slapped the cuffs on talent agent boyfriend Mark Rousso by getting engaged.

Mark helped Melissa, 47, cope with the death of her comedy legend mom and “Police” predecessor, Joan Rivers, last September.

“She’s beyond excited after all they’ve been through this year,” said a pal, adding Melissa’s gotten the seal of approval from her 14-year-old son, Cooper, with first hubby John Endicott.

“Melissa saw how much Joan struggled with being a single mom after her husband’s suicide. She loves the idea of having a real family again, and wants Mark to be a big part of it,” added the pal.
