Andre Ethier -- Hello Kitty Puts Butts ... In Dodger Stadium!

She can't hit ... she can't field ... but no one packs Dodger Stadium like Hello Kitty ... and Andre Ethier knows it.

It's true ... the Dodgers have been doing a Hello Kitty giveaway night for years -- and they're always extremely popular.

In fact, Hello Kitty nights have SOLD OUT since 2011 ... and some of the giveaways (including a Dodgers-themed Hello Kitty plush doll) have become collectibles worth serious cash.

So, when we saw Ethier at Madeo in Bev Hills this week ... we asked if he was gonna try to get his hands on the Hello Kitty bobblehead the team is giving away on June 3rd.
