With the dinner being held tonight, we are re-upping our posts from this week previewing the festivities.

The White House Correspondents' Dinner is Saturday, with festivities starting Thursday and lasting all weekend. The annual funniest/glitziest/most over-done night in Washington will be full of self-deprecating laughs and selfies with celebrities.

Here's what we know about it so far.

"Saturday Night Live" comedian Cecily Strong will host. You might remember her as "Girl You Wish You Hadn't Started a Conversation with at a Party" and for her stint as a "Weekend Update" host.

Strong said she doesn't "want to be too mean where it really hurts somebody" with her jokes, and wants to make everyone laugh (bipartisanship!). In other words, don't expect another Stephen Colbert.

"I'd rather do things we can all laugh [about]," she told Capitol File. "I'd like to be able to make fun of myself as much as anyone else. I don't want to make fun of the way someone looks -- things like that. Children are off-limits. There are definitely people in that room who I respect and admire a lot."

She also said there were certain things she wanted to get into, without giving specifics.

"I know I definitely want some great, hard jokes," she told Variety. "There are definitely certain issues I'd love to hit and spend a little more time on. I think I'm kind of a silly person, so I hope it's a little more silly than truly biting, if that makes sense. Really, I just hope that some of it is funny to some people -- that would be the goal. I want to break even. That is what I keep saying because all I keep hearing is how tough a room it is, so it would really feel like a win if I break even."
