Barbara Marx Sinatra (née Blakeley; born March 10, 1927) is an American former model and showgirl who became the fourth and final wife of Frank Sinatra (from 1976 until his death in 1998).

Early years

Blakeley was born in 1927 in Bosworth, Missouri, one of two daughters of Charles W. Blakeley and his wife, the former Irene Prunty Toppass (died 1993, California). Her family relocated to Wichita, Kansas, where she was raised. In her autobiography, Lady Blue Eyes, Barbara Sinatra states that she celebrated her 70th birthday in March 1997 (page 347).

Personal life

She first married Robert Harrison Oliver, an executive with the Miss Universe pageant, in the mid- to late-1940s, a marriage which produced a son, Robert "Bobby" Oliver, but ended in divorce.

She became a Las Vegas showgirl in the 1950s, also modeling clothing for famed fashion designer, Mr. Blackwell.

While working in Las Vegas, she met Zeppo Marx, and, on September 18, 1959, they married. Barbara's son, Bobby, assumed the family name of his stepfather. It was presumed at the time that Bobby Marx had been legally adopted by Zeppo Marx, but Tina Sinatra has claimed that, according to Robert Harrison Oliver, no such adoption took place. Barbara and Zeppo divorced in 1973.
