Jennifer Love Hewitt Cleavage Joke: Actress Embarrassed by Jimmy Kimmel (VIDEO)

Actress Jennifer Love Hewitt became the victim of one of Jimmy Kimmel's jokes Wednesday while appearing on the talk show to promote her new show "The Client List."

"The Ghost Whisperer" actress received a dose of humiliation after falling victim to one of Jimmy famous  pranks. The talk show host was quick to address the billboards that are currently circulating to promote the actress' new Lifetime show "The Client List."

Kimmel commented that the star's cleavage took up a large portion of billboard space. Kimmel referred to the risqué ad as "maybe the greatest ad campaign I've ever seen for a television show."

While Hewitt seemed to handle the comments lightly, Kimmel took it one step forward and then posted a picture of the ad on a massive screen. The only part of the ad that was blown up, however, was Hewitt's cleavage.

"It looks like a horror movie [when it's] blown up like that...they're like King Kong's," a rather embarrassed Hewitt prompted.

A day before the show, the actress decided to tone it down the a bit and posted a picture of herself on Twitter going for a more natural look, with out any make-up.

"The no make up look... Glam look to follow," the 33-year-old Client List star tweeted Tuesday.

In the picture Hewitt appears to be wearing her hair halfway back, with a lazy gray sweatshirt and a make-up free face. The 33-year-old actress also stars in "Hot in Cleveland."

While the star is currently not dating anyone, she has expressed an interested in Maroon 5 singer Adam Levine. Levine recently split from Victoria's Secret model Anne Vyalitsyna.

"I always have my eyes out," Hewitt said on the Ellen DeGeneres show when asked about dating. "I just read two days ago that Adam Levine is single again … I'm just saying."
