is at husband Nick Cannon's bedside
again – but this time she has better news.
"Nick is in stable condition with a good prognosis, hopefully he'll be discharged within 2 days," the singer Tweeted
Friday, adding, "As always he's laughing and in good spirits."
Just as she did on Wednesday, when Cannon was hospitalized with what she termed "mild kidney failure"
, Carey also posted a photo
of her cuddling up to Cannon in his hospital bed.
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."
