I think this is Anna’s most high-profile event since she officially split from Chris Pratt, and I imagine there was some pressure — internally or otherwise — to have a GRAND OLD TIME and just pretend none of that other stuff exists. But it’s possible that may have caused her to go… well, overboard, frankly, with the displays of public joy. Having said that, it IS all very Goldie Hawn of her, so maybe she’s just channeling the spirit of her forebears?
