"Actress Susan Sarandon and her partner of 23 years, actor Tim Robbins, have announced that they separated over the summer," Sarandon's rep Teal Cannaday said in a statement to ABCNews.com. "No further comments will be made."
Immediately rumors spread that Sarandon was dating her 31-year-old business partner, Jonathan Bricklin, but Cannady quashed those.
"The rumors are absolutely untrue," Cannaday told ABCNews.com. "Susan's relationship with Jonathan Bricklin is strictly a business one."
Though they never married, the couple have two sons together, Jack, 20, and Miles, 17. Sarandon also has a daughter, Eva Amurri, from her 1980s relationship with director Franco Amurri.
This spring, Sarandon told Entertainment Weekly that being single was "exhilarating and terrifying at the same time," and that she was open to dating again.
"I think the point is just keep moving, and to just say yes to life," she said.
