In court documents filed Tuesday, Dina, 48, cites irreconcilable differences as the reason for the breakup. The former reality star is also seeking custody of the couple's only minor child, 16-year-old daughter Morgan.
Clint, 83, married Dina in 1996. The two first met when Dina was assigned to interview him for a local TV news station. This marked Clint's second marriage, as he was married to Maggie Johnson from 1953 to 1984, and also had a long-term relationship with actress Sondra Locke throughout the 1970s and 1980s.
