The pair appeared to be in high spirits as they happily chatted and shared a laugh when leaving Beverly Hills hotspot Mr. Chow, reported Ace Showbiz.
During the outing, Carey wore an ankle-length, black dress. Cannon, meanwhile, looked classy in a white shirt paired with burgundy blazer.
After their night out, the four headed back to Carey's home.
The "I Don't" hitmaker posted on Instagram an adorable photo of them snuggling in bed.
She could be seen reading her twins a bedtime story while their dad slept next to them. "#bedtimestories #demkids #family @nickcannon (sic)," so she captioned it.
