Age is just a number to One Direction's Harry Styles.

After running into former "Bachelorette" Jillian Harris in Los Angeles on April 2, 2012, the bold, 18-year-old heartthrob hit on the reality star, 32, and even asked her for her digits.

Harris politely turned him down.

"Jillian feels awful [that this has gotten out]," a source close to Harris tells Us Weekly. "He's adorable, but eighteen is a bit too young for her."

Had Harris said yes, it wouldn't be the first time Styles has gotten involved with an older woman: the British pop star has also been linked to 32-year-old U.K. TV personality, Caroline Flack.

Though she wasn't quite ready for a night on the town with the underage crooner, Harris assures Us she's honored Styles considers her crush-worthy. Says Harris, "I was super flattered!"
