Jennifer Love Hewitt shocked by breasts picture on Jimmy Kimmel
Kimmel surprised the actress with the image, reportedly taken from one of the billboards promoting Love Hewitt's show The Client List.
She jokingly tried to cover the image and quipped: "Oh my God, seriously, that looks like a horror movie - my boobs coming towards you!
"They're like King Kong's or something. Oh my God, let's not."
Love Hewitt also joked that she has heard from "lots of people that I haven't heard from in years" after the billboards began to go up across the country and admitted that seeing the adverts is "kind of weird" but "cool".
"My family is pretty proud," she added. "Thank God none of them have been put in my grandmother's neighborhood yet, so I'm waiting for that phone call and hoping that it won't happen.
"She asked me, 'What are you wearing in the posters?' And I'm like, 'I'm wearing a bathing suit'. And she's like, 'OK! Well, that's great! So is it in spring?' And I was like, 'Yeah, it's coming out in spring, so don't even worry about it'. Hopefully she won't see it!"
Love Hewitt has previously revealed that she was "confused" when she saw the print ad for The Client List as it has been retouched to give her a breast reduction.
She has also said that she does not want to strip off for her role in the show, which airs Sundays at 10/9c on Lifetime.
