The songstress was serenaded and the guest list was star-studded at Liza Minnelli's bridal shower.

Donna Summer, Natalie Cole and Valerie Simpson performed "You Are So Beautiful to Me," said Warren Cowan, publicist for Minnelli's fiance, producer David Gest, on Thursday. Socialite songwriter Denise Rich was the host of Wednesday's shower at her Fifth Avenue penthouse.

Among the 70 guests were Janet Leigh, Patricia Neal and Jane Powell, contemporaries of Minnelli's mother, Judy Garland. The bride's best friend, Marisa Berenson — a maid of honor at Saturday's wedding, along with Elizabeth Taylor — was there, as were The View co-hosts Joy Behar, Star Jones and Meredith Vieira.

Minnelli, who turned 56 on Tuesday, and Gest, 48, are marrying at the Marble Collegiate Church. The marriage will be Minnelli's fourth and Gest's first.

Michael and Tito Jackson will be the best men at the ceremony, and Whitney Houston will sing "The Greatest Love of All" as Minnelli walks down the aisle in a Bob Mackie gown. The bridesmaids, who will be dressed in black, include Mia Farrow, Gina Lollobrigida and Petula Clark.
