Groban and Jones in March
After three years together, pop balladeer Josh Groban and actress January Jones (American Wedding) are "taking a break" from one another, his rep, Liz Rosenberg, tells PEOPLE.
Other than saying, "They remain friends," Rosenberg had no further comment.
Jones's rep, Dominique Appel, also had no comment.
Jones, 28, was spotted this past weekend with Lukas Haas and other pals at the Light nightclub anniversary party in Las Vegas. Jones and Haas star in the new movie Swedish Auto, opening at the Los Angeles Film Festival this week.
The former Abercrombie & Fitch model – who once dated Ashton Kutcher – will next appear in the Matthew McConaughey film We Are Marshall, in which she plays the wife of Matthew Fox's character.
Groban, 25, released his second studio album, Closer, in 2004 – the same year he appeared in the Super Bowl half-time show. Unfortunately, his performance was upstaged by the antics of Justin Timberlake and Janet Jackson.
He is currently back in the recording studio working on his latest CD, to be released this fall, says Rosenberg.
