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.
"It's obvious they were up to no good," said an onlooker.
