Just as she did on Wednesday, when Cannon was hospitalized with what she termed "mild kidney failure"

In the latest picture, which is captioned "Thank you everyone for all the love & concern," Carey is smooching Cannon on the cheek while he grins. The couple is surrounded by flowers and get-well balloons.
The update is good news – on Wednesday Carey had revealed to PEOPLE that her husband was in ""a lot of pain."
