Former tennis ace Bjorn Borg is resting at his parents' home outside Nice, France, and re-emphasizing that his overdose of sleeping pills Tuesday was "only a stupid accident." The Swede and his girlfriend, Italian pop star Loredana Berte, arrived Thursday night at La Sevigniere, the seaside villa he bought his parents several years ago. "I never intended to put an end to my days," Borg said Friday. "It was in fact sleeping pills that caused unbearable nausea. So I called my doctor, who advised me to go immediately to a clinic in Milan." Borg and Berte had planned a church wedding for Feb. 26 and the overdose incident prompted speculation that Borg tried to take his life because the Roman Catholic Church would not allow the ceremony.
