First Lady Michelle Obama teamed up with basketball star Lebron James and his teammates from the Miami Heat for a new ad to promote healthy eating as part of the first lady's "Let's Move" campaign.

The ad, which premiered on "Good Morning America" on Tuesday, features Miami Heat players Dwayne Wade and Ray Allen and Head Coach Erick Spoelstra talking about the importance of eating healthy.

But the first lady, James and Chris Bosh make cameos of their own - photobombing Wade and Allen by eating apples, drinking water, and even dunking a small basketball behind them as they speak.

The ad was filmed last week at the White House when President Obama honored the Miami Heat for winning their second NBA championship in a row.
