After more than a year of dating, Paula Abdul
and her restaurateur boyfriend JT Torregiani have split due to their hectic work schedules, his rep tells PEOPLE exclusively.
"It became too hard to maintain the relationship," says Torregiani's rep, who adds: "They remain best of friends."
The couple began dating in 2006 and were spotted last June celebrating her 45th birthday
together at Torregiani's West Hollywood eatery, Ketchup, where he spent the entire night by her side.
Last summer, Abdul described her romantic life
to Today show host Matt Lauer as "a horror movie" but noted that "things are looking good right now."
