This weekend, Liza Minnelli will wed producer David Gest in front of a star-studded gathering in New York City. On March 13, the couple sits down with "Dateline" anchor Jane Pauley for an exclusive interview where the two share details about their upcoming nuptials, Liza's recent health problems and her anticipated comeback.

The March 16 wedding marks the fourth time that the Tony, Oscar and Emmy-winning actress-singer will walk down the aisle. Minnelli's first marriage to the late entertainer Peter Allen ended in 1972. She wed Jack Haley, Jr. — son of "Wizard of Oz" Tin Man Jack Haley — in 1974, and her third marriage to sculptor Mark Gero also ended in divorce in 1992.

NBC News' "Dateline" airs 8 PM (ET) March 13. Check local listings for time and channel in your area.

More than 300 stars, including such luminaries as Michael Jackson, Elizabeth Taylor, Petula Clark and Whitney Houston, are expected to attend the wedding, which is being held at Wall Street's The Regent after a ceremony at the Marble Collegiate Church. Dozens of the guests are also expected to perform at the reception.

The 55-year-old Minnelli is the daughter of the late, famed actress Judy Garland and director Vincente Minnelli. A performer since a young child, Minnelli has conquered the worlds of stage, recordings, film and television and is perhaps best known for her screen work as Sally Bowles in the Academy Award-winning film of Kander and Ebb's "Cabaret." Minnelli, who was last on Broadway in her one-woman show, Minnelli on Minnelli, has battled various health problems in the past few years. Fiancé Guest, however, promises to bring Minnelli back to her former glory, which begins with a European concert tour in April. Among Minnelli's Broadway credits are Flora, the Red Menace, The Act, Chicago, The Rink and Victor/Victoria.
