Nothing funny about this. 

Jim Carrey's 24-year-old daughter Jane filed for divorce from hubby Alex Santana Thursday, Us Weekly confirms. Jane, who married Santana in Nov. 2009, cited irreconcilable differences as the reason for the split. She is seeking joint legal and physical custody of the couple's 20-month-old son Jackson.

Jim, 49, confirmed his daughter's separation from her husband of one year in Dec. 2010. "The couple will remain friends, as well as devoted parents to their [son] Jackson Riley," his rep, Marleah Leslie, told Us at the time.

Jane is Jim's only daughter from his marriage to Melissa Womer from 1987 to 1995. He was also married to Dumb and Dumber costar Lauren Holly from 1996 to 1997.
