A.J. LANGER & CHARLES COURTENAY
The My So-Called Life star met her future husband, who she would go on to discover was the Earl of Devon, in Vegas while at a bachelorette party in 2002. Courtenay was a lawyer visiting from Britain with his rugby team.
"We caught eyes and smiled. The kilt was a novelty. The smile was all I needed," Langer told PEOPLE. For his part, "We instantly got on like a house on fire," said her husband, whom she wed in 2005. "We went out to a nightclub — I wasn’t allowed in because I was wearing a skirt! So we spent a bit of time walking around the streets and got to know each other really, really well."

For the designer-turned-director, "love at first sight" was something he experienced when coming face-to-face with his now-husband on an elevator ride almost 30 years ago.

MATTHEW & CAMILA ALVES MCCONAUGHEY
Although the Oscar winner was "happily single," things all changed when he set his eyes on Brazilian beauty Camila. "Out of the corner of my eye, this sort of aqua-green figure went floating across the frame about 20 feet in front of me," he told PEOPLE of seeing Alves for the first time nearly a decade ago. "My eye went up and I remember what came out of my mouth. I didn't say 'Who is that?' I went, 'What is that?' As l was trying to get that's attention across the room, I went in my head, 'This is not the kind of woman you call over across the room, McConaughey. Get your ass out of your chair and go get her.' Which I did." As for what immediately drew the actor to Alves, McConaughey – who fronts PEOPLE's 100 Reasons to Love America issue – was quick to respond: "The self-respect she had, the way I understood her and her relationship with family, the way she respected me but never took anything for granted, not putting on any airs whatsoever."
