Jennifer Love Hewitt may have to hang up some of those risque "Client List" costumes -- because she's pregnant!

The 34-year-old actress and boyfriend/costar Brian Hallisay are expecting their first child together.

"This is a wonderful time and we are looking forward to starting our family together," the couple tells toofab.

She is reportedly three months along, according to an Us Weekly source.

The two, who actually met on the set of the short-lived NBC show "Love Bites," have been together for about 15 months.

Jennifer recently dropped $3.25 million on a new home in the Pacific Palisades -- hope there's room for a nursery!

In the past, Hewitt was engaged to Ross McCall and dated her "Ghost Whisperer" costar Jamie Kennedy. No word yet on if Jennifer and Brian have any plans to tie the knot.

Congrats to the happy couple!
