What do I know, but I'd never heard of him until tonight. Interesting. A hugely successful, gay Israeli pop singer.
How I found out about him was: tonight I was watching the latest Chelsea Lately show, and Chelsea had singer Katy Perry on as her guest. (Show was really funny, BTW.) Perry is famous for "I Kissed a Girl." I wanted to post a video of her singing the song and found this video by Ivri Lider. Nice. Hope you like it (if you haven't already seen it).
Here's the "Jesse" video.
