Who Makes Jamie Lee Curtis Blush?

ET visited the set of NCIS for a behind-the-scenes look at tonight's episode featuring Jamie Lee Curtis and found out who makes the Freaky Friday actress blush—Mark Harmon.

"I'm very fond of him and he's fond of me" Curtis said of her friendship with Harmon. "I'm not going to lie to you and say that this is a horrible, difficult job to 'play' with him.
I'm happy to have it."

Curtis face filled with a slight flush as she then tried to speak more on the topic. "He makes me blush a little bit," she then admitted, "because he's just such a sweet guy."

In addition to gushing over Harmon, Curtis revealed that she has thought about doing her own television series.

"My children are raised [now] so I could clearly see myself doing more regular work now," the 53-year-old actress said.
