When Jennifer Love Hewitt revealed she had the hots for Adam Levine, she never dreamed he'd ever find out.

But the newly single Maroon 5 frontman, 33, did hear about her crush -- and he's charmed. "It's very, very flattering," Levine told Access Hollywood Wednesday. "It's very flattering and very sweet. It was lovely to hear."

Levine then smiled and said, "But I'm not going to let it get to my head."

The Voice mentor may not be ready to get into another relationship just yet. A source recently told Us Weekly that he was "blindsided" when model ex Anne Vyalitsyna announced their split to the world April 2.

"It was a cheap shot," a Levine pal explained. "Anne didn't want it to look like he broke up with her."

Levine is "heartbroken," the pal added. "He wasn't even fully sure they were really broken up."
