They had a daughter named Atiana Cecilia age 17.
Moakler started dating boxer Oscar de la Hoya in October 1997 and they moved in together in early 1998. Moakler and de la Hoya became engaged prior to the 1999 birth of their daughter, Atiana Cecilia de la Hoya (born March 29, 1999). Moakler has said "it wasn’t a planned pregnancy, but it was understood if it happened it was beautiful and if it didn’t that was fine too." In September of 2000, the relationship abruptly ended when Moakler, who was at home watching the Latin Grammy Awards on television, saw de la Hoya escorting another woman to the show. In December of 2000, Moakler filed a $62.5 million palimony suit against her ex-fiancé, claiming he was an alcoholic, abusive to her and to their daughter, and that he used them "as props to promote his public image." The case was settled out of court in 2001 for an undisclosed amount. After the time of de la Hoya`s split from Moakler, he had little contact with his daughter, although he continued to provide financial support.
