Calvin Klein and Brooke Shields — who famously got her start at age 15 in his provocative 1980 jeans campaign — reunited at the American Ballet Theatre Fall Gala on Thursday.

Spies said the duo “had a fun reunion and reminisced about her famous campaign.”

Elizabeth Olsen — whose mother was a professional ballerina — was particularly excited to see the night’s performance of “Daphnis and Chloe” as choreographed by Natalie Portman’s husband, Benjamin Millepied.

Other attendees at the David H. Koch Theater included Julianna Margulies, Katie Holmes, Maggie Gyllenhaal, Victor Cruz and Julia Koch.
