90's star of the classic "Party of 5" and most recently Lifetime's "The Client List" star Jennifer Love Hewitt is expecting her first child.

Hewitt and her boyfriend and co-star, Brian Hallisay began dating 15 months ago when Hallisay began playing the character Kyle Parks on the Lifetime drama. What originally began as a recurring role for the actor turned into a more permanent position as a series regular.

"We're so thrilled and happy to start a family," Hewitt and Hallisay told Us Weekly in a statement Tuesday. According to the magazine, the actress is three months pregnant.

Before dating Hallisay, Hewitt was previously in a relationship with actor Ross McCall, who she met on the set of the series, "Ghost Whisperer," in 2005. They became engaged in November 2007, but ended their engagement late the following year. In March 2009, Hewitt began dating her "Ghost Whisperer" co-star, Jamie Kennedy. They broke up after a year of dating.

Back in 2010 during a conference call with press in 2010, Hewitt, who has long been the subject of pregnancy speculation, joked , "The paparazzi has been saying I'm pregnant for four years now and I have yet to pop out a baby! They've kind of already done that with me so I feel that when the moment comes, they'll say, 'We don't care -- you've been pregnant for eighteen years!"
