The couple allegedly exchanged vows in Vegas at the Simple Wedding Chapel, a famous quickie marriage spot with Elvis Presley impersonators as witnesses.
TMZ Online has obtained the marriage license filed at Clark County Recorder's Office. The paperwork shows the daughter of Clint Eastwood and Frances Fisher tied the knot with Feldstein, the manager of Maroon 5 and Robin Thicke, on November 17.
Francesca, 20, had been dating Feldstein for quite sometime now.
Despite the marriage report, there was no wedding ring in sight when Francesca attended Miss Golden Globe Party recently. She was named Miss Golden Globe this year and passed the torch to Kevin Bacon and Kyra Sedgwick's daughter Sosie Bacon for next year's awards ceremony.
