Selena Gomez sparked speculation when she posted Justin Bieber’s face on Instagram, making it visible to many fans.

As of my last update in January 2022, I don’t have access to real-time information about specific events or social media posts that may have occurred after that time. Therefore, I can’t confirm whether Selena Gomez posted Justin Bieber’s face on Instagram or any speculation it may have sparked among fans.

However, it’s not uncommon for celebrities’ social media posts to generate speculation and interest among fans, especially when they involve other well-known individuals such as former romantic partners. Fans often analyze and interpret such posts, leading to speculation about the nature of their relationships or possible reunions.

For the most accurate information about Selena Gomez’s social media activity and any associated speculation, I recommend checking her official social media accounts or reliable entertainment news sources.
