What better way to celebrate an engagement than with a romantic dinner date?
They arrived Thursday at around 10:15 p.m. and McCarthy was proudly sporting her new sparkler.
“She looked stunning and was wearing a navy blue jump suit,” said an onlooker.
The couple were extremely lovey-dovey. She placed her feet in his lap the entire evening and they were deep in conversation throughout the night.
“They looked extremely happy and in love. They were kissing and whispering to each other all night,” said the source.
Wahlberg and McCarthy started dating last summer. This will be the second marriage for both.
