Chelsea Clinton and beau split

NEW YORK, Sept. 1 (UPI) -- Former first daughter Chelsea Clinton has apparently called it quits with boyfriend Ian Klaus, People magazine reported Thursday.

Clinton, 25, spent several months in London working on a public health care project while Klaus, 26, was working as a journalist in Iraq and Afghanistan.

"They just grew apart," a friend of Clinton's told the magazine.

Clinton recently spent a week vacationing on the Hawaiian island of Kauai with her parents.
