The on-again, off-again marriage of Latin singer Marc Anthony and former Miss Universe Dayanara Torres appears to have wrapped up for good.

Torres, 29, filed for the dissolution of her three-and-a-half year marriage to Anthony, 35, on Jan. 20 in Miami-Dade County, Fla., PEOPLE reports in its upcoming issue.

Calling their union "irretrievably broken," Torres is seeking alimony and child support for the couple's two sons, Cristian, 2, and Ryan, 5 months. (Anthony also has a daughter, Arianna, born in 1994, whose mother is his former girlfriend Debbie Rosado.)

In December 2002, after having separated for five months, Torres and Anthony renewed their vows in a lavish ceremony at the San Juan Cathedral in Puerto Rico. The marital hiatus -- which did not entail a legal separation -- had begun 26 months after the couple's first wedding in Las Vegas.
