Hayden Panettiere's Bikini -- In a Tight Spot

And now ... some photos of Hayden Panettiere in a really small,wedge-tastic bikini ... because it's summer.

Hayden hit the beach in Cabo San Lucas, Mexico this week ... showing off her tiny physique as she tanned by the pool.

Hayden's NFL player BF Scotty McKnight was there too ... no shirt, no problem.
