According to E! News, the "Skyfall" singer looked "cute and casual" for the outing with her son, and was joined by a female friend at one point.
Though Adele has been consistently private regarding her new bundle of joy -- she hasn't even confirmed the baby's name publicly -- it's fair to assume she's very happy to have a boy based on what she told Vogue in an October 2011 interview:
"I've always got on better with boys. Most of my friends are boys. Like, if I ever have children, I want five boys," said the star.
"Boys love their mothers," she added, "whereas girls can be so mean to each other."
