[4] Annabel Edith Villagra was born on February 14, 1936, in Nueve de Julio, a town southwest of Buenos Aires, Argentina.

She was a pre-medical student at the University of Buenos Aires, then left at age 20 in 1956 after marrying Eduardo Battistella, a pianist who played in clubs.

Although their marriage had collapsed, she allowed her husband to live with her in the Crystal Towers complex in Arlington County, Virginia, because, as she told The Washington Post, "I don't like him to spend money, and he is the father of my children.

In August, Mills moved with his wife into the Crystal Towers complex, where they frequently played contract bridge with Foxe and her husband.

While being driven back by a friend, the car they were in was observed speeding, swerving, and driving without headlights by the Washington, D.C. waterfront near the Jefferson Memorial at around 2:00 a.m.[5] The United States Park Police pulled the vehicle over, and Foxe panicked, got out of the car screaming in a mix of English and Spanish, and attempted to flee the scene by jumping into the Tidal Basin, which had an average depth of 10 feet (3.0 m).

[6][7] In later interviews, Foxe said she jumped because she wanted to protect Mills's reputation and was worried that the incident would affect her recently acquired American citizenship.

Apparently drunk, Mills showed up and unsteadily walked onstage, prompting Foxe to say "Ladies and gentlemen, I have a visitor for you, and he wants to say hello.

"[5] Mills then gave a rambling speech onstage and then a backstage news conference in which he angrily announced that Foxe would no longer be performing.

[5] On December 10, 1974, Mills stepped down from his position as chairman of the Ways and Means Committee and did not run for re-election in 1976, ending a 38-year congressional career.

[3] After the Mills incidents, Foxe continued working as a stripper, changing her stage title from "The Argentine Firecracker" to "The Tidal Basin Bombshell".

When hired by Michael Pinter Jr. for a December 1974 show at Club Juana in Orlando, Florida, she increased her fee for a two-week stint from $3,500 to $15,000 per week.

[5][6] In 1981, she gave an interview to The Washington Post in which she spoke about being upset that Mills claimed not to remember what he was doing during his affair, and was particularly hurt by his saying that he had "learned not to drink with foreigners".
