Tamra and Shannon, along with all of the other current RHOC cast minus Kelly Dodd, were in attendance for Andy's big day.
It appeared to be a wonderful time for all who attended the event that celebrated Andy's impending fatherhood.
Shannon and Tamra kept the party going into the night after they left Craig's in West Hollywood.
The ladies were clearly enjoying their time out as they did a little dance on the way to their car.
Craig's is a place that Shannon is fond of, as she was previously seen in high spirits when leaving the celeb hotspot with Kelly earlier this year.
Tamra kept the party going when she got into the car. She flashed double peace signs in an interesting seating position before they headed out for the evening.
