The now-grown children of two of my favorite artists. Some clues:
Their mother is back in the news and was an icon of my teen years - at one point I thought she was the most beautiful woman on Earth. My favorite of her albums was released 25 years ago this past summer. She was not solo then, but left her famous group eventually. Their father is a pop music legend. He can sing too, but he's not known for that. He has written, literally, like 40 of the greatest pop songs of the past 30 years. Both children are musical.
The brothers with some girls. The (older) one on the right is pictured below.
