Ryan Seacrest took a break from hosting his radio show and executive producing “Keeping Up with the Kardashians” for a new role that he took just as serious: Man of Honor. People reports that Seacrest’s younger sister Meredith got married on Saturday in Mexico with her big brother by her side, allowing him to assume the role of a traditional maid of honor. The day before the wedding, Ryan made sure that his sister’s dress was ready to go. And on the day of the wedding, he and sissy had a morning workout and he proudly flashed his Man of Honor placard. Ryan and Meredith are pretty tight, she is the executive director and COO of the Ryan Seacrest Foundation. But this put the icing on the cake for cute sibling love.
