Malibu beach Paris Hilton, River Viperi shopping summer dress

Paris Hilton and beau River Viiperi hit Malibu for the 4th of July holiday ... where else would the heiress celebrate?!

The cute couple visited the Malibu Country Mart Friday for some shopping after the previous evening of fireworks and fun.

The both looked adorable in matching bright, turquoise blue -- fit for a magazine cover, we think! But we can't help wondering ... could the next magazine cover for Paris be Bride?
