Ryan Seacrest Was a Man of Honor at His Sister's Wedding

Ryan Seacrest's sister, Meredith, got married this weekend to TOMS senior executive Jimmy Leach. The television producer served as man of honor, and naturally, he killed it.

The beautiful bride, who tied the knot in Mexico on Saturday in front of friends and family, shares Entertainment Tonight, asked Seacrest to play the role with an adorable poem-posal back in October of last year.

The siblings clearly have a strong relationship, making the gesture even sweeter.

For the celebration, Seacrest donned a bright blue suit with a tie that matched the bridesmaids' dresses (which, by the way, is a great way to help your honor attendant stand out without breaking color scheme). The American Idol host took to Instagram to congratulate the newlyweds, giving us a better look at his polished getup. Meanwhile, Meredith stunned in Vera Wang, reports Entertainment Tonight.

And according to Seacrest's social media shout-out, both he and the groom's respective fashion brands helped out with the wedding style.

Best of all, it looks like he was more than present during the planning stages, even accompanying Meredith to pick up her dress …

… and for a pre-wedding workout.

Glad you're following our checklists, Seacrest!
