sunglasses Paris Hilton airport lax hat River Viiperi leather jacket

Paris Hilton and her equally gorgeous beau River Viiperi arrived back home from Mexico with big smiles and lots of luggage.

Love that both are rocking leather jackets. Biker-chic, baby!

While the twosome were south of the border, Paris snapped super sexy pics in her tiny bikini. Talk about stunning!

These two are still going strong after almost a year, and we couldn't be happier for them!
