Justin Long and Drew Barrymore have ended their romance, the actor’s publicist said Tuesday.

“I just wanted to confirm that, yes, they did break up,” Carrie Gordon told The Associated Press in a phone interview, adding that the couple remain friends. She didn’t give further details.

Barrymore, 33, and Long, 30, co-star in the movie adaptation of the self-help best-seller “He’s Just Not That Into You,” slated for release next February.

The split comes as a surprise, given their public displays of affection since they began dating last year.

The lanky actor seemed smitten with the actress-producer, escorting her to red-carpet events including Madonna and Gucci’s “A Night to Benefit Raising Malawi and UNICEF” party in New York City in February.
