Jon and Kate Gosselin, stars of the popular TLC reality series Jon & Kate Plus Eight, will announce on Monday that they will file for divorce, according to Radaronline.com. The website is reporting that a source confirmed that Kate recently met with a divorce lawyer, and the couple had previously decided to separate by mid-July, but is now moving up the timetable. TLC has scheduled a special one-hour edition of the show for Monday; in a teaser spot for that episode, Kate says, "We've made some life-changing decisions." (The parents of eight are contracted for 40 episodes this year.)
