People.com: Looks like there's a baby boom in New Jersey!

Teresa Giudice, one of the stars of The Real Housewives of New Jersey, is pregnant with her fourth child, a Bravo rep confirms to PEOPLE exclusively. The reality star is five and a half months along, and is "excited" about expanding her family.

Giudice, 36, already has three daughters -- Gia, 8, Gabriella, 4, and Milania, 3 -- but is unsure about the sex of her new baby. According to Bravo, Giudice "wants to keep it a secret until she delivers."

But Giudice isn't the only expectant Housewife. PEOPLE confirmed in April that castmate Jacqueline Laurita is expecting her third child this summer.
