The 43-year-old bride has invited several of her famous friends including her Modern Family co-stars.

Everyone having fun is Sofia's main priority. It's no secret that the Hot Pursuit star is going all out with her nuptials and the entertainment is a big factor.
"To me, it's not all about perfection but all about fun," Sofia told E! News. "Great music, great alcohol and great food. It's a Latin party, we go until late. There's a party and an after party."
The Colombian beauty, who is a self-confessed cake addict, also revealed that the wedding cake and the desserts table will be a highlight of the reception.
As for the decor, Nolan Gould, who plays Luke Dunphy on Modern Family, dished: "Sofia's very flamboyant and she likes things big. I'm not giving specifics, but there might be animal-print tablecloths!"
