Alastair Stewart is the 18-year-old son of Penny Lancaster and Rod Stewart. Rod has six other children from previous relationships, in addition to Aiden Stewart. Many Stewarts have taken to Instagram to congratulate Alastair on his appearance in the Milan fashion campaign.
The seventh Stewart child signed a deal with luxury clothing brand Palm Angels, which resulted in his face being plastered across Milan on signs and billboards. Rod posted the billboard on Instagram with the caption, “Love @palmangels and that my boy ‘wears it well.’”
