During Sunday night's episode of Watch What Happens Live, Patti LaBelle said that Prince treated her like she was his mother while the two collaborated on her 1989 album, Be Yourself.

"He treated me like he was my son [and] I was his mother," recalled LaBelle. "He just treated me like his mother. And then when he did the Arsenio Hall Show, he said he wouldn't do it unless I came with him. So I came, sat on the couch, I didn't say a word. He had this great feeling for me and I feel so proud and blessed."

She added that she once cooked a meal for Prince, but that he only ate a single biscuit before taking LaBelle out dancing at a nightclub.
