That girl's got a glow about her! Jessica Simpson looked absolutely stunning as she and fiance Eric Johnson strolled through Los Angeles International Airport on Sunday, Oct. 13. The singer, 33, donned sky-high black boots, a deep-cut black top and sparkly grey blazer for her airport attire.

She accessorized with an oversized black leather bag in the crook of her right arm and a pair of large sunglasses, with her long blonde hair in waves around her face. Johnson, meanwhile, kept his look casual-chic as well, in a dar navy button-down, brown slacks and dark brown loafers.

Simpson kept her left arm firmly intertwined with her former NFL star beau as the pair made their way through the terminal.

Just one day earlier, the happy mother-of-two (to daughter Maxwell, 16 months, and son Ace, 3 months) looked similarly gorgeous as she walked down the aisle at longtime publicist Lauren Auslander's wedding in Newport, R.I.

Simpson shared a few precious snapshots from the event, including one particularly sweet one of her with Johnson's mother.

"Beautiful morning with my future mother-in-law and MoJo to my babies!" she captioned the shot, in which Simpson and her future mother-in-law share matching grins and oversized shades.

Simpson and Johnson, 34, got engaged in November 2010.
