When friends go on vacation for a much-needed break, the only thing they should worry about is packing enough sunblock and giving themselves ample time to get ready before hitting the clubs.

Unless, of course, you're Silver (Jessica Stroup) and Adrianna (Jessica Lowndes), and the boy you are fighting over is on vacation with you in steamy Mexico. Looks like their feud reaches the boiling point, right in front of Navid (Michael Steger), but does someone actually take a swing?
Looks like Silver does! But it's not so much as a swing, but a full-on push! If we know good television, then we predict someone is going into that pool. Who do you think will come out on top of this catfight? Don't worry, you'll find out April 18 when 90210 returns with an all-new episode, awesomely titled "The Enchanted Donkey."
