Maybe she thought she was sending a text?
Mariah Carey posted a very revealing photo on her Twitter page around 2:30 AM today -- along with a seductive message to her husband, Nick Cannon.
Happy Birthday to my Hubby @NickCannon..."my baby I'm waiting on youuuu"hahaha! KKLB! GHL!!!! Mwah !!!!!— Mariah Carey (@MariahCarey) October 8, 2013
We have no idea what those two acronyms mean (though fans speculate), but the attached photo shows Mimi busting out of her open top while wearing a black lace bra.
Cannon, who turns 33 today, has yet to respond to his wife on Twitter, but we're guessing he was in a hurry to get home this morning!
The 43-year-old is no stranger to showing some skin -- check out some of her most revealing looks in the gallery below.
