The iconic musician was seen carrying what appeared to be a D&G shopping bag while walking into a Los Angeles recording studio Monday morning.
John's London-based publicist told ET in a statement, "Yes he was carrying the bag but he hadn’t been shopping and it should not detract from their original message or the boycott."
John called for the boycott after D&G designers Domenico Dolce and Stefano Gabbana made negative comments about babies born by in vitro fertilization and non-traditional families.
When Domenico Dolce and Stefanio Gabbana spoke with the Italian publication Panorama magazine, Dolce said, "You are born and you have a father and mother. At least it should be like that. That's why I'm not convinced by what I call children of chemistry, synthetic children. Rented wombs, semen chosen from a catalog."
John took to Instagram to slam the designers, saying, "How dare you refer to my beautiful children as "synthetic"… Your archaic thinking is out of step with the times, just like your fashions. I shall never wear Dolce and Gabbana ever again. #BoycottDolceGabbana"
A number of stars soon joined in one the boycott, including singer Ricky Martin and Glee creator Ryan Murphy.
It’s unclear if John's choice to carry the Dolce & Gabbana bag will impact his newly created cause.
