Jennifer Love Hewitt just learned a valuable lesson: Don't reveal your private crushes in public!

"The moment when you make a comment about something or someone and the world makes you feel like a total fool. #keepcrushesquiet," the star of "The Client List" tweeted moments ago.

The "someone" in question: Maroon 5 frontman Adam Levine.

Earlier this month, Hewitt told Ellen DeGeneres she had her eyes on Levine now that he's single again ... and said she thought they'd make a "cute" couple.

Watch her original statements below:

Then yesterday, Adam appeared on Ellen as well -- where she asked if he had heard Hewitt's comments.

He said he did and joked JLH was "aggressive," fueling her embarrassment. Watch Adam's appearance below:

After seeing his interview though, Hewitt tweeted "Thank you to @adamlevine for being so gracious on Ellen about my crush heard round the world. I've learned a lesson.#Sssh"

She added "Am I dating? Am I crushing? No! I'm directing The Client List season finale!;)"
