She may be Cammie's cousin, but she's much more like a sister to both her and Ryan

Not only is he Ryan's best man, but he's also officiating the wedding. Need we say more?

She was Cammie's roommate (and BFF) for all four years of college

Better known as "Wys," he was roommates with Ryan and Cammie, and would hide in their room to scare them at night

Cammie and Lainy got mistaken for each other all of college (Some say they're long lost twins)

If the After Party gets a little rowdy, you can blame it on this guy, better known as "Bear"

She was one of Ryan's best friends before Cammie stole her away

Another tall volleyball player.. shocker! Try not to mistake him for Ryan at the wedding.

Kat is the queen of tequila! Take a shot with her at the reception

Cammie and Olivia walked down the aisle together at high school graduation

The man, the myth, the legend

One of Cammie's oldest friends and a budding tax strategist (Update: Apparently, this is *not* what she does for work. Who knew?)

She's the mother of Cammie's second favorite guy (5-year-old Bruce!)

Brother in law #1: This one likes smoking meat, playing with his son Bruce, and receiving pictures of Jenny

When Ryan initially told his family that he had a girlfriend, Haley immediately knew it was Cammie!

Brother in law #2: This one likes the zoo, golf, and craft beer
