The couple were spotted grinning ear-to-ear while attending Hart's Laugh Out Loud launch event in Beverly Hills on Thursday.
Parrish, 32, showed off her fast-growing baby bump while looking stunning in a navy blue mini dress.
Hart looked dapper in a slick maroon suit.
As Radar previously reported, Hart, 38, was accused of cheating on his pregnant wife, 32, earlier this month.
The comedian was spotted hooking up with Miami-based model Monique Gonzales inside car.
"It's obvious they were up to no good," said an onlooker.
