Looks like Alexa Ray Joel's broken heart is on the mend: The singer, 24, who told PEOPLE that her despair over a failed romance led her to be hospitalized last December, has a new boyfriend. He is singer-songwriter Cass Dillon.
The pair met when Dillon, 24, was hired to play guitar on Joel's upcoming album. (To listen to her first single, "Notice Me," click here.) "Dating can be awkward," Joel said in April. "I prefer to meet someone through work or socially."
