Another day in paradise, another smokin' hot bikini pic from Paris Hilton!

The heiress and her boyfriend River Viiperi are currently on vacation in Mexico, and they flew in with several pals on Friday. While Paris is loving life at the pool and the beach, she had a photo shoot and several interviews yesterday, so it's a bit of a business trip as well.

P tweeted, "How do you like my hot pink tiny bikini? ;)." Um, we love it, obvi!
