Confidential Lady ended the undefeated record of the favored Germance at Chantilly on Sunday, overcoming a troubled trip for a 1 1/2-length victory in the $1 million Prix de Diane, or French Oaks. Trapped on the rail entering the three-furlong stretch, Confidential Lady was angled out by jockey Seb Sanders for a clear run, of which she took utmost advantage, speeding to the line in 2:05.90, equaling the stakes record set in 1985 by Lypharita and within 0.1 of a second of the track mark for 1 1/4 miles, set by Darsi in last Sunday's Prix du Jockey-Club. French bettors let Confidential Lady, trained by Mark Prescott, get away at 43-1, unaware that she clearly takes after her sire, turf champion Singspiel. Queen Cleopatra, an Aidan O'Brien-trained filly who was the only other foreign-based entry in the 16-strong field, was nosed out for the runner-up spot by Germance, whose four previous victories include the Group 1 Prix Saint-Alary.
