Kevin Bacon Posts Thirst Trap to Celebrate 66th Birthday |

Kevin Bacon is still feeling sexy well into his 60s ... because he's fishing for likes with a bare-chested photo.

The actor is celebrating his 66th birthday today and he's marking the occasion with a topless thirst trap ... showing off his abs, which are still there.

Kevin's posing outdoors somewhere, leaning back on what appears to be a rock near the base of a bluff ... and it looks like he has swim trunks on, so he may be near a beach.

Seems Kevin even had someone block out the sun here to get the photo lighting just right ... he may have a future as an Instagram influencer.

KB captioned the thirst trap ... "This is 66" with a birthday cake emoji.

The post is working, if it's indeed an attention grab ... he's getting tons of birthday love and the replies are mostly filled with flattering comments.
