Jessica Alba caught herpes from an ex-boyfriend, it has been claimed.
The 'Fantastic Four' star - recently voted FHM's Sexiest Woman Alive 2007 - previously dated New York Yankees baseball star Derek Jeter and during their relationship she allegedly contracted the sexually transmitted disease.
A source who worked as Jessica's assistant at the time claims they had to replenish her Valtrex prescription - a treatment for genital herpes - on a regular basis, according to website L.A. Rag Mag.
Jeter has also dated Mariah Carey, Vanessa Minnillo and most recently Justin Timberlake's new girlfriend Jessica Biel.
Seventy percent of herpes spreading is said to happen when there is no sign of infection, according to an STD awareness campaign.
Jessica, 26, recently split from lover Cash Warren because he wouldn't marry her. The 'Sin City' actress, who reportedly called time on their two-and-a-half year romance during an emotional telephone conversation last month, grew tired of waiting for the movie producer to propose.
A source said: "He wasn't ready for marriage, and Jessica is. It's as simple as that. It's kind of cold that people are saying she has just finished with him, because it isn't like that."
The pair met on the set of the first 'Fantastic Four' film in 2005, in which Jessica starred and Cash worked as a director's assistant.
