-- Sinead O'Connor has been located by police, authorities confirmed to ABC News.
According to a statement from law enforcement, she was found this afternoon and "is no longer listed as missing or endangered."
No other details were available.
Police near Chicago confirmed earlier today that they were "seeking to check" on the well-being of the O'Connor, who was last seen on Sunday shortly before she went on a bike ride.
The "Nothing Compares 2 You" singer was last seen yesterday in the suburb Wilmette. According to the Wilmette Police Department, "O'Connor reportedly left the Wilmette area for a bicycle ride yesterday at 6:00 a.m. and has not returned. A caller has expressed concern for her well-being, and no other information is available at this time."
O'Connor, 49, recently made scathing accusations against TV host Arsenio Hall in relation to Prince's death. Hall responded by suing her for $5 million for defamation.
She called the lawsuit "laughable," and writing, "I'm more amused than I've ever dreamed a person could be and look forward very much to how hilarious it will be watching him trying to prove me wrong."
Shortly before her bike ride, O'Connor posted on Facebook about her son Jake. "Do not abandon your brother or any other of my babies again," she wrote in a rambling post.
She has been married four times and has three other children. She has put together 10 studio albums, including one billed as her comeback in 2014, "I'm Not Bossy, I'm the Boss." The album hit No. 1 in her native Ireland and No. 83 on the Billboard top 200 in the U.S.
A representative for the singer told ABC News earlier today that there's no information about O'Connor "at this time. But will keep you posted."
