The stars, who played one of Hollywood's most endearing couples in the 1970 romance, were thrilled to welcome 91-year-old George Hiller to the stage at the The Wallis Annenberg Center for the Performing Arts.

O'Neal tells, "He is a wonderful director who really made Love Story work. We haven't seen him for years, and it was wonderful to reunite and know that he came to watch us perform together here at the Wallis."

O'Neal and MACGraw opened their tour of Love Letters in Fort Lauderdale, Florida in July (15).
