Jamie Lynn wore a "tight-fitting white dress with an ivory coat for the outing, and rocked blonde hair extensions."
"The kids were all so excited to see each other and be there. They were having fun sucking on lollipops and running around," the insider adds to Us. "It was a fancy restaurant but they tried to keep it very low-key."
Britney opted for a black dress and matching black jacket.
"Britney seemed very happy with her boyfriend and was holding his hand and kissing him," the source adds. As for the soon-to-be bride and groom, "Jamie Lynn and Jamie were very mellow and spent most of the evening chatting with friends."
