Paris Hilton Opening Up ... About Her Chest

2/3/2015 5:15 AM PST

Paris Hilton hasn't been very open about alleged massive changes to her boobs ... luckily her robe is plenty open. 

While she's refused to talk about her chest ... she's still sharing A LOT of it in this super hypnotic selfie she posted.

Either Paris is REALLY good with makeup -- there's a lot of it in the pic -- or those whappers are doctor-enhanced. 

But try to look away ... even the picture on the wall can't stop staring.

Boob-gate continues ...
