Serena Williams

The groom isn't the only one who rolls with a crew of It Girls. First up on the bride's side of things is a tennis star you may have heard of. Meghan and Serena Williams became fast friends after meeting back in 2014 at a celebrity football game, and have remained close ever since. Meghan was reportedly invited to Serena's wedding but missed it due to scheduling conflicts while she was still filming Suits. Serena, however, cleared her schedule for this major event - recently pulling out of this week's Italian Open so she could be in London. No word yet on whether her husband, Reddit co-founder Alexis Ohanian, will be joining her.
