Cheryl Hines and Robert F. Kennedy Jr. are planning to tie the knot!
"Yes, they are engaged," a source close to the situation tells PEOPLE of the couple, who began dating in 2012.
This will be the second marriage for Hines, 48, and the third for Kennedy, 60, whose second wife, Mary, committed suicide in the family's Bedford, New York, home in May 2012.
The Suburgatory star sang the praises of her environmentalist beau at an event in L.A. in March.
"I really like this guy," she said at the UCLA event that honored the attorney, calling the father of six "a devoted dad and an all-around good guy."
