Jennifer Love Hewitt Pregnant: 'Client List' Actress and Co-Star Brian Hallisay Expecting (PHOTOS)

Actress Jennifer Love Hewitt has confirmed to US Weekly in a statement that she is expecting her first child with her "Client List" co-star, Brian Hallisay.

"We're so thrilled and happy to start a family," she said.

A source told US Weekly the star is three months along in her pregnancy and is about to enter her second trimester.

Hewitt and Hallisay began dating 15 months ago after reconnecting on the set of their Lifetime show, and previously appeared together on the now-canceled NBC show, "Love Bites."

Hewitt was previously engaged to actor Ross McCall, who she began dating in 2005, but broke it off in 2008. Hewitt and Hallisay are both 34, and the actress has always been adamantly vocal about her desire to settle down, get married and have children.

"I would love to to have babies...one day," Hewitt said Us Weekly in 2010. "I'm obsessed with babies!"

Now it looks like her dream has finally come true. The star's announcement comes a year after she lost her mother, Patricia, to cancer. A source told US Weekly in March that Hewitt was considering having her eggs frozen to prolong her fertility over the years, as she was allegedly afraid she would end up childless.

"[She] feels worried that she will end up single, since none of her relationships have been successful," the source said to the gossip magazine. "If it doesn't work out with Brian, then she can still be a mom one day."

And if Hallisay wants to get engaged, Hewitt already has a list of potential engagement rings picked out. In an interview with Ellen DeGeneres in 2011, Hewitt admitted she had made a list of three Tiffany engagement rings picked out in advance, so whoever proposed to her would be one step ahead of the game. At the time of the interview, Hewitt was dating actor-director Alex Beh, but the two soon split up.
