We'll never understand Courtenay Semel.

One moment, the useless socialite is making out with occasional lesbian Tila Tequila; the next, she's all over fashion designer Wayne Joffe.

The two were spotted out together in celebration of Semel's birthday earlier this week. While we can't confirm a hook up between the pair, a source states that Joffe "may be a jazzbo."

We'll have more news on that possibility as it breaks, but this much is certain: Semel is one angry Q-list celebrity...

Chill out, Courtenay Semel. You posted these pics on your own Facebook account.
