So that's what she looks like under all the makeup!
Bethenny Frankel went au naturel on Twitter on Monday, showing what she looks like with barely any makeup on her face.
"This is my 'it's Monday' face, which looks very similar to my 'I'm exhausted and it's only Monday' face," the talk show host tweeted along with the photo, where it appears she's only wearing mascara.
She immediately got props from her fans and followers, who applauded her for "keeping it real" on the social network.
And she's got a good reason to be so "exhausted" -- today, she turns 100!
The former "Real Housewives of New York" star's talk show airs its 100th episode on Tuesday, with visits from Hoda Kotb, Tamar Braxton, Loni Love and Maksim Chmerkovskiy.
