The 29-year-old "Younger" star has revealed she is planning a backyard party for her only child Luca - who she has with her former partner Mike Comrie - when he turns five on March 20, which will see entertainers dressed as characters in the science fiction film, reported E! News.
"We're doing a backyard party, which I haven't done since he was two. I think the Ghostbusters are showing up. It's going to be like a whole thing," Duff says.
