ADD lippy Lisa Rinna’s name to the ever-growing list of design shows.

Rinna, the former “Days of Our Lives” star, will host a new Lifetime series called “Merge,“ in which she’ll help newly married couples “merge” their belongings into one harmonious household. The show kicks off in September.

Rinna is basing her hosting duties on personal experience – hubby Harry Hamlin (“L.A. Law”) who “thinks he’s like the designer of the century, and he is, he’s really good,” Rinna told TV critics gathered in L.A.

“I’ve had to fight my whole entire relationship with him to bring a picture frame into the house,” Rinna said of Hamlin. “My husband lets me do nothing at our house.”
