Cameron Diaz & A-Rod's Chance Encounter With George Clooney

Nothing more fun than lunchtime in the sun than when a surprise guest shows up to say hi! Cameron Diaz and Alex Rodriguez just so happened to run into George Clooney in Cabo San Lucas, Mexico on Tuesday while they were enjoying a meal. George is also vacationing in Mexico right now, with galpal Elisabetta Canalis.

Meeting such big stars must be fun for A-Rod's daughter, Natasha, who also seems to be bonding with Cam!

George looked excited to see friends, and maybe like he was even ready to play one of his famous pranks, holding something that looked like it could be launched at someone else... maybe some ice?
