Jennifer Love Hewitt's Breasts Steal the Show on 'Jimmy Kimmel Live'

Jennifer Love Hewitt got a big surprise last night during an appearance on “Jimmy Kimmel Live.”

On the late night talk show to promote “The Client List,” a new Lifetime series in which she plays a single mom who turns to prostitution to support her children, Kimmel told the 33-year-old actress that a huge billboard for the show — with her cleavage front and center — had been directly outside of his office window. The prankster host then had a staffer carry out a “gift” for the star — a square section of the billboard, which had recently been taken down, featuring just a close-up shot of her breasts.

Ever the good sport, Hewitt, who covered her face with her hand in embarrassment, joked, “Seriously, that looks like a horror movie blown up… They’re like King Kongs or something.”

Extending her arms in an attempt to cover the massive poster, she said, “Let’s just… Let’s not.”

Although she may have blushed a little last night, this morning Hewitt was still laughing at Kimmel's joke. “Had the best time on jkl!,” she tweeted on Wednesday from the set of her show. “I took the boob billboard and the cast and crews will love it! so funny!”

Another recent share on Twitter? On Tuesday, the actress posted a photo in which she appears without a stitch of makeup. Wearing a gray shirt and her hair down, her face glowed despite not using any cosmetic products on her famous face.

While she was all about her bare face in the photo, the star recently said she has no plans to share her exposed body on camera — ever. “I wouldn't have done nudity, no,” she said while promoting the show at a press event. “That's not something that I feel particularly comfortable with… I also think that it's sexier not to show everything. I feel like imaginations can do way more.”
