The 25-year-old English singer was joined by her 13-month-old baby boy Angelo, who relaxed in a stroller.
This was the first time Adele and Simon have been spotted together since February.
“[Adele] knows now I’m a superfan. She’s so sweet. She’s my big favorite to work with just because I’m a huge fan. She told me she was a big fan, too, and gave me some advice. She said, ‘Girl, don’t have a baby ’cause everything else will go on the back burner,” Kelly Clarkson recently shared to Us Weekly.
