Stars collide as ET goes inside a posh bridal shower for a "Without a Trace" actress!

CBS star Roselyn Sanchez is getting married and Eva Longoria Parker was just one of her A-list friends to attend the party, thrown by Roselyn's gal pal and co-star Poppy Montgomery.

It was a Latin-themed shower for the Puerto Rico native, who noshed on quesadillas, Orville Redenbacher lime and salt flavored popcorn, and of course, mojitos.

The day also included soothing spa treatments and tarot card readings.

Roselyn and her fiance Eric Winter will say "I do" on November 29.
