Instagram is currently abuzz with a fascinating new trend powered by Google’s Nano Banana AI tool. Officially part of Gemini Nano Banana (Flash Image Model 2.5), the feature allows users to merge their own photos with images of Bollywood and Hollywood stars, producing ultra-realistic selfies. From walking the red carpet with Shah Rukh Khan to sipping coffee with Priyanka Chopra in Paris, the tool is making it look like fans are actually hanging out with their idols.

What Exactly Is Nano Banana?

Nano Banana is Google’s latest AI-powered image generation feature designed to simplify photo creation. Unlike traditional photo editors that require manual adjustments, this AI tool uses text prompts and advanced blending to create seamless, life-like pictures.

The process is simple: users upload their own selfies and pair them with a celebrity photo. Within seconds, Nano Banana generates a composite image that looks convincingly authentic. For Instagram users, this is nothing short of a dream, as it delivers scroll-stopping content that feels as though you’ve shared a candid moment with your favorite star.

How to Create Your Celebrity Selfie Using Nano Banana

If you’re tempted to jump into this viral trend, here’s a quick guide to getting started:

1. Open the Gemini app or website and sign in with your Google account.

2. Select the Nano Banana Image Creation option.

3. Upload your selfie along with the photo of your chosen celebrity.

4. Enter a text prompt to describe the scenario. For example:

   • “Create a selfie of me with Shah Rukh Khan at a film premiere.”

   • “Make a Polaroid-style picture of me and Virat Kohli in Indian jerseys at a cricket stadium.”

5. Hit Generate and wait a few seconds.

6. Save your AI-generated celebrity selfie and share it on Instagram or other platforms.

The results are remarkably realistic, often indistinguishable from actual photos, which explains why the feature has taken Instagram by storm.

Why This Trend Is Taking Off

The rise of this trend is driven by a blend of curiosity, fandom, and the ever-growing appetite for unique content on social media. Users are thrilled by the chance to visualize their dream interactions with global icons, creating moments that would otherwise be impossible.

For many, the appeal lies in the hyper-realism Nano Banana provides. Whether it’s a coffee date with a Hollywood star or a candid airport picture with a Bollywood celebrity, the AI outputs images that could easily pass as genuine.

The Legal and Ethical Angle

While the fun element is undeniable, experts warn about the legal and ethical considerations surrounding such tools. In India, Article 21 of the Constitution protects an individual’s right to privacy, meaning that using a celebrity’s image without permission could potentially violate their rights.

Similarly, in the United States, states like California have strict laws governing the digital recreation of celebrity likenesses, even for deceased personalities. Using AI to generate such content without consent may land users in legal trouble.

Technology companies are aware of these risks and are actively working to limit misuse. Google, for instance, once paused human image generation in its Gemini AI tool to prevent harmful use cases. Other firms deploy prompt filters that block attempts to create content imitating specific individuals.

A Fun Yet Responsible Trend

Despite the concerns, Nano Banana continues to gain momentum among Instagram creators and casual users alike. The tool is being hailed as a playful way to experiment with AI, provided users stay mindful of the boundaries of consent and digital ethics.

As AI technology becomes more mainstream, such tools will likely become a regular part of how people create, share, and interact with digital content. For now, though, Nano Banana selfies remain one of the most talked-about trends of 2025—blurring the line between fantasy and reality with just a click.
