Eva Longoria's headed south of the border to tie the knot this weekend with fiance Jose Baston!

The Telenovela actress, 41, will wed the Latin media chief Baston, 47, at the beachside vacation home of Jane the Virgin star Jaime Camil. The guest list will be star-studded, of course -- most notably, Eva's BFF Victoria Beckham and hubby David will be there. As will Katy Perry, Ricky Martin, Penelope Cruz, Mario Lopez and more.

The couple were engaged in December, while on vacation in Dubai and have dated for about three years.
