Going out to ABC Cocina for the night, Jennifer was apparently "in a great mood laughing and chatting with her girlfriends" with her ring on full display, E! News reports.
"Jennifer wore her engagement ring and it was very noticeable and sparkly. She was smiling and laughing throughout the meal. It was clear she's very happy and was having a great night."
After J.Law confirmed her engagement earlier in the month, she was spotted with a plain band on her ring finger, which made fans believe she had turned the ring inwards to hide it.
Jen and Cooke were first spotted together in June 2018, and since have been seen on holidays, romantic dinners and walks together.
The pair were reportedly introduced to one another through one of her good friends.
So happy for her!
