Kanye West — All Smiles After Kim K. Engagement

Kanye West strolled into his hotel this afternoon in San Francisco … just hours after proposing to baby mama Kim Kardashian — and the guy looked REALLY HAPPY!

West was in such a great mood, he even threw out a peace sign to the photogs snapping his pic — it”s almost like he got laid last night or something.

Congrats pal … on the engagement (and on the getting laid thing).
